Perf improvements to Task/Task<T>

- Remove some unecessary intermediate functions, e.g. Execute(), manually inlining it into its one caller
- Make the common completion path (no exceptions, no cancellation, etc.) more inlineable, and avoid calling some functions (like AddExceptionsFromChildren) when we know they will be nops.
- Make FinishContinuations inlineable.  When there aren't any continuations, this shaves off a measurable percentage of time.  When there are, we're no worse off, as the FinishContinuations entrypoint gets inlined, so we still only have the one function call to RunContinuations.
- Make TaskCompletionSource.TrySetResult more inlineable.  It was just on the cusp, with an extra branch / call to IsCompleted putting it over the edge.  But the common path for calling TrySetResult is when the call will successfully transition, in which case we don't need the IsCompleted call; it's only necessary if/when we lose the race condition, in which case we can pay a bit more to call SpinUntilCompleted.
- Avoid some duplicate logging-related calls
- Remove AggressiveInlining from an ETW-related method that did not need it; the call sites can instead just check IsEnabled before calling it.
- Remove some unnecessary writes, casts, locals, etc., make some fields readonly
- Change CompareExchange to Exchange in Task.WhenAny completion

Commit migrated from https://github.com/dotnet/coreclr/commit/f45a33639d7d8ab1bfcda6de7b5cb74abb95662a

Streamline AsyncTaskMethodBuilders

- Slim down AsyncTaskMethodBuilder`1.Task and make it aggressively inlined.  The common case we care to optimize for is synchronous completion, in which case the first access to Task will already fine m_task non-null, and we want that access inlined.
- Slim down AsyncTaskMethodBuilder`1.SetResult.  As with Task, we care most about the synchronous completion path, as when perf matters, most async method invocations complete synchronously.  The code path is streamlined so that the synchronous completion path can mostly be inlined.
- Replace some throws with ThrowHelper
- Mark GetTaskForResult as aggressive inlining.  It contains a lot of C# code, but for a given TResult, the JIT trims away the majority of the implementation.

ARM64 Modify genCodeForInitBlk assert

Assert in codegenarm64 was incorrect for the GT_STORE_DYN_BLK oper.
If it is that oper then there will not be a temp reg used and instead
the size is computed and stored into REG_2. Add an assert to assert
this is done.

Use DynamicSecurityMethod attribute to mark methods with StackCrawlMark

CoreCLR does not have CAS, and so we can conveniently use it to mark methods with StackCrawlMark to
decouple it from NoInlining. The original purpose of DynamicSecurityMethod was to disable inlining
of the caller and to insert CAS security checks, so we are basically just keeping the first part.

Fixes dotnet/coreclr#8102
