Remove unnecessary use of volatile in PartitionerStatic (dotnet/corefx#39591)

`SharedInt`, which is just an object wrapper around a `volatile int` was being used even though a) the objects weren't actually being shared, and b) the stored `int` was sometimes being passed by `ref` and thus losing its voliatility in some cases anyway.

(It's not entirely clear why an object is being used, regardless, but from the comments it appears to be due to concerns around false sharing.  Presumably cases were found where the enumerators were all allocated up-front resulting in these ints stored as part of the enumerator objects ending up on the same cache line, so they were moved to objects allocated on discrete threads during MoveNext to minimize that possibility.)

Avoid "async void" tests (dotnet/corefx#39613)

Most of these are just because "async void" tests are rare and require special handling in xunit we needn't use.  But a few of these are plain wrong and were resulting in our not actually testing what we hoped to test.

Fold a bunch of CoreCLR's abandoned mutex tests into a parameterized test (dotnet/corefx#39050)

Fold a bunch of CoreCLR's abandoned mutex tests into a parameterized test

- There are a large number of tests in CoreCLR with a lot of redundancy, timing issues, and which take unnecessarily long to run
- Folded a bunch of them into the existing parameterized test and improved it to cover more cases to replace the tests in CoreCLR that will be removed
- Coverage is not 100% equivalent, but I belive this sufficiently covers the necessary aspects of the tests in CoreCLR that will be removed

Propagate abort exceptions from CreditManager.Dispose (dotnet/corefx#39520)

Currently, if an abort occurs, it disposes of credit managers, and if there's a waiter on that credit manager, that waiter propagates an ObjectDisposedException.  It should instead propagate whatever exception resulted from the abort.

More Win7 EventLog retries (dotnet/corefx#39521)

Remove hooking of system color changes (dotnet/corefx#39468)

* Remove hooking of system color changes

Hooking user preference changes to update system colors is expensive, particularly as it is hooked via reflection. Getting the current color from the OS is extremely cheap.  Removing this layer of caching avoids creating a watcher window and thread and a significant number of startup allocations.

In starting up a blank WinForms app this cuts 200 allocations.

Note that Pens and Brushes in System.Drawing start their own user preference watcher so that they can update GDI+ when backed by system colors.

Remove unnecessary "internal" from JsonConverterFactory ctor (dotnet/corefx#39504)

The ctor is already `protected`, so it can already be accessed by any derived type.  The only benefit adding `internal` would provide is so that it could be called directly by something else in the assembly, but the type is `abstract`, so that doesn't make sense for a ctor.

Ensure that CancellationToken is propagated to built-in request content types (dotnet/corefx#39474)

* Ensure that CancellationToken is propagated to built-in request content types

We don't currently expose the overload that would allow CancellationToken to be accessed by HttpContent-derived types in general, but we can at least ensure that when using the built-in content types, the CancellationToken provided to SendAsync is appropriately threaded through.  We were doing this previously in only a few cases, where we knew that the previous overload wouldn't be overridden (namely internal types and sealed types), but we can enable the 90% scenario as well by doing a type check at run-time.
