Improve Monitor scaling (#14216)

Improve Monitor scaling and reduce spinning

Part 1: Improve Monitor scaling

Fixes https://github.com/dotnet/coreclr/issues/13978
- Refactored AwareLock::m_MonitorHeld into a class LockState with operations to mutate the state
- Allowed the lock to be taken by a non-waiter when there is a waiter to prevent creating lock convoys
- Added a bit to LockState to indicate that a waiter is signaled to wake, to avoid waking more than one waiter at a time. A waiter that wakes by observing the signal unsets this bit. See AwareLock::EnterEpilogHelper().
- Added a spinner count to LockState. Spinners now register and unregister themselves and lock releasers don't wake a waiter when there is a registered spinner (the spinner guarantees to take the lock if it's available when unregistering itself)
  - This was necessary mostly on Windows to reduce CPU usage to the expected level in contended cases with several threads. I believe it's the priority boost Windows gives to signaled threads, which seems to cause waiters to much more frequently succeed in acquiring the lock. This causes a CPU usage problem because once the woken waiter releases the lock, on the next lock attempt it will become a spinner. This keeps repeating, converting several waiters into spinners unnecessarily. Before registering spinners, I saw typically 4-6 spinners under contention (with delays inside and outside the lock) when I expected to have only 1-2 spinners at most.
  - It costs an interlocked operation before and after the spin loop, doesn't seem to be too significant since spinning is a relatively slow path anyway, and the reduction in CPU usage in turn reduces contention on the lock and lets more useful work get done
- Updated waiters to spin a bit before going back to waiting, reasons are explained in AwareLock::EnterEpilogHelper()
- Removed AwareLock::Contention() and any references (this removes the 10 repeats of the entire spin loop in that function). With the lock convoy issue gone, this appears to no longer be necessary.

Perf
- On Windows, throughput has increased significantly starting at slightly lower than proc count threads. On Linux, latency and throughput have increased more significantly at similar proc counts.
- Most of the larger regressions are in the unlocked fast paths. The code there hasn't changed and is almost identical (minor layout differences), I'm just considering this noise until we figure out how to get consistently faster code generated.
- The smaller regressions are within noise range

Part 2: Reduce Monitor spinning

Fixes https://github.com/dotnet/coreclr/issues/13980
- Added new config value Monitor_SpinCount and Monitor spins for that many iterations, default is 30 (0x1e). This seems to give a somewhat decent balance between latency, fairness, and throughput. Lower spin counts improve latency and fairness significantly and regress throughput slightly, and higher spin counts improve throughput slightly and regress latency and fairness significantly.
  - The other constants can still be used to disable spinning but otherwise they are no longer used by Monitor
- Decreased the number of bits used for tracking spinner count to 3. This seems to be more than enough since only one thread can take a lock at a time, and prevents spikes of unnecessary CPU usage.

Tried some things that didn't pan out:
- Sleep(0) doesn't seem to add anything to the spin loop, so left it out. Instead of Sleep(0) it can just proceed to waiting. Waiting is more expensive than Sleep(0), but I didn't see that benefit in the tests. Omitting Sleep(0) also keeps the spin loop very short (a few microseconds max).
- Increasing the average YieldProcessor() duration per spin iteration improved thorughput slightly but regressed latency and fairness very quickly. Given that fairness is generally worse with part 1 of this change above, it felt like a better compromise to take a small reduction in throughput for larger improvements in latency and fairness.
- Tried adding a very small % of lock releases by random wake a waiter despite there being spinners to improve fairness. This improved fairness noticeably but not as much as decreasing the spin count slightly, and it was making latency and throughput worse more quickly. After reducing the % to a point where I was hardly seeing fairness improvements, there were still noticeable latency and throughput regressions.

Miscellaneous
- Moved YieldProcessorNormalized code into separate files so that they can be included earlier and where needed
- Added a max for "optimal max normalized yields per spin iteration" since it has a potential to be very large on machines where YieldProcessor may be implemented as no-op, in which case it's probably not worth spinning for the full duration
- Refactored duplicate code in portable versions of MonEnterWorker, MonEnter, and MonReliableEnter. MonTryEnter has a slightly different structure, did not refactor that.

Perf
- Throughput is a bit lower than before at lower thread counts and better at medium-high thread counts. It's a bit lower at lower thread counts because of two reasons:
  - Shorter spin loop means the lock will be polled more frequently because the exponential backoff does not get as high, making it more likely for a spinner to steal the lock from another thread, causing the other thread to sometimes wait early
  - The duration of YieldProcessor() calls per spin iteration has decreased and a spinner or spinning waiter are more likely to take the lock, the rest is similar to above
- For the same reasons as above, latency is better than before. Fairness is better on Windows and worse on Linux compared to baseline due to the baseline having differences between these platforms. Latency also has differences between Windows/Linux in the baseline, I suspect those are due to differences in scheduling.
- Performance now scales appropriately on processors with different pause delays

Part 3: Add mitigation for waiter starvation

Normally, threads are allowed to preempt waiters to acquire the lock. There are cases where waiters can be easily starved as a result. For example, a thread that holds a lock for a significant amount of time (much longer than the time it takes to do a context switch), then releases and reacquires the lock in quick succession, and repeats. Though a waiter would be woken upon lock release, usually it will not have enough time to context-switch-in and take the lock, and can be starved for an unreasonably long duration.

In order to prevent such starvation and force a bit of fair forward progress, it is sometimes necessary to change the normal policy and disallow threads from preempting waiters. A new bit was added to LockState and ShouldNotPreemptWaiters() indicates the current state of the policy.
- When the first waiter begins waiting, it records the current time as a "waiter starvation start time". That is a point in time after which no forward progress has occurred for waiters. When a waiter acquires the lock, the time is updated to the current time.
- Before a spinner begins spinning, and when a waiter is signaled to wake, it checks whether the starvation duration has crossed a threshold (currently 100 ms) and if so, sets ShouldNotPreemptWaiters()

When unreasonable starvation is occurring, the lock will be released occasionally and if caused by spinners, spinners will be starting to spin.
- Before starting to spin, if ShouldNotPreemptWaiters() is set, the spinner will skip spinning and wait instead. Spinners that are already registered at the time ShouldNotPreemptWaiters() is set will stop spinning as necessary. Eventually, all spinners will drain and no new ones will be registered.
- After spinners have drained, only a waiter will be able to acquire the lock. When a waiter acquires the lock, or when the last waiter unregisters itself, ShouldNotPreemptWaiters() is cleared to restore the normal policy.
