99db31c41d5057e08cc4701c79f11246b9191a9b appears to have a potential issue because the order of MarkThreadRequestSatisfied and Dequeue are reversed. For instance, assuming a proc count of 1:

- T1 Dispatch: dequeues a work item and requests a thread (0 work items, 1 thread request)
- T1 Dispatch: sees no more work items, returns
- T1 calls Dispatch again due to its own thread request
- T1 Dispatch: After Dequeue (which saw 0 work items) and before MarkThreadRequestSatisfied:
  - Current state: 0 work items, 1 thread request
  - T2 enqueues a work item, sees 1 thread request and does not request a thread (1 work item, 1 thread request)
- T1 Dispatch: MarkThreadRequestSatisfied decrements thread requests (1 work item, 0 thread requests)
- Now after T1 returns, it won't wake up again but there is still one work item in the queue

Improve ReaderWriterLockSlim scalability

Fixes #12780

The _myLock spin lock runs into some bad scalability issues. For example:
- Readers can starve writers for an unreasonable amount of time. Typically there would be more readers than writers, and it doesn't take many readers to starve a writer. On my machine with 6 cores (12 logical processors with hyperthreading), 6 to 16 reader threads attempting to acquire the spin lock to acquire or release a read lock can starve one writer thread from acquiring the spin lock for several or many seconds. The issue magnifies with more reader threads.
- Readers and especially writers that hold the RW lock can be starved from even releasing their lock. Releasing an RW lock requires acquiring the spin lock, so releasers are easliy starved by acquirers. How badly they are starved depends on how many acquirers there are, and it doesn't take many to show a very noticeable scalability issue. Often, these acquirers are those that would not be able to acquire the RW lock until one or more releasers release their lock, so the acquirers effectively starve themselves.

Took some suggestions from @vancem and landed on the following after some experiments:
- Introduced some fairness to _myLock acquisition by deprioritizing attempts to acquire _myLock that are not likely to make progress on the RW lock
- Limited spinning in some cases where it is very unlikely that spinning would help

PGI: Load pgort<ver>.dll from the VS native tools env; do not `install` it (#12581)

On Windows, PGO instrumented builds (build.cmd release <arch>
pgoinstrument) introduce a runtime dependency on pgort<ver>.dll for
instrumented binaries. This DLL is distributed alongside the C++
compiler, and is made available via the native tools environment that
ships with Visual Studio.

Previously, we were using cmake to find and "install" this binary
alongside the product when doing an instrumented build, so that the
resulting bin\Product drop is free of any added external dependencies.
However, this approach is fragile, and despite a best effort to make the
implementation work across multiple VS releases, it already broke with
VS 2017.

To fix support for pgoinstrument on VS 2017, and to harden the
implementation for future releases of VS, I'm removing the custom cmake
install logic for the pgort DLL. Instead, we fall back to the officially
supported method: load the correct (native tools) environment before
invoking any command that uses an instrumented binary. This happens in
one place in the build today--loading the JIT to crossgen
System.Private.CoreLib.dll.

Note that there's still an existing CLI/Setup bug that requires copying
the pgort DLL. We're now doing it from within build.cmd, which is not
nearly as fragile for this as cmake is. The workaround is also isolated,
so when the referenced issue is fixed, the workaround (as documented)
can simply be removed.

Fixes #12347.
