Fix MulticastInterface_Set_ValidIndex_Success failures on non-Windows platforms. (dotnet/corefx#9471)

This test assumed that the "loopback" interface was always at index 1, which is not true on Linux/OSX/etc.  This change makes that assumption explicitly Windows-only, while allowing the "any interface" case to run on all platforms.

Reduce System.Threading.Tasks.Tests from ~140s to ~10s

As with https://github.com/dotnet/corefx/pull/9468 and https://github.com/dotnet/corefx/pull/9466, this commit focuses on reducing the total, outerloop running time of our worst-offending test suites.  This one is on the System.Threading.Tasks tests.  Some of the tests are not in good shape, e.g. it's not clear to me that the TaskCancelWaitTests are actually verifying everything they should, even though they're spending a lot of time doing it.

Changes:
- Reduced artificially long wait times in TaskAwaiter, IAsyncResult, TaskCancelWaitTests, TaskStatusTests, CESchedulerPairTests, and Coverage tests
- Reduced size of workload in TaskCancelWaitTests, TaskContinueWithAllAnyTests, and TaskWaitAllAnyTests
- Ensured that the ThreadPool was ramped up to serve several tests expecting more threads available
- Removed some unnecessary spinning

Reduce System.Threading.Tests from ~650s to ~8s

As with https://github.com/dotnet/corefx/pull/9466, a few tactical changes to significantly reduce the outerloop running time of the System.Threading.Tests suites (lots of work could be done to further improve/overhaul these tests, but that wasn't my goal):
- Two barrier tests were taking several minutes.  Reduced the number of iterations from 10,000 to 10.  A few iterations helps to verify intended behavior; more than that is a stress test that doesn't belong in the functional suite.
- Reduced explicit timeouts in a ReaderWriterLockSlim test
- Reduced timeouts in some SemaphoreSlim tests.  As part of this I split up a few tests into [Theory]s in order to help identify where the actual problem was.
- SpinLock tests were getting throttled by the ThreadPool; changed them to use new threads rather than pool threads.  As with above, I also split some of these tests into [Theory]s to help identify where exactly the problem was.

Commit migrated from https://github.com/dotnet/corefx/commit/8148702e8c356c41f837fc248c178506811f8407

Reduce System.Threading.Tasks.Parallel.Tests from ~200s to ~6s

Various areas of these tests could really stand to be rewritten.   This commit does not attempt to do that.  Rather, my goal was to significantly reduce the running time of the tests.  Today, with outerloop enabled, they take ~200 seconds.  This commit gets that down to ~6 seconds.

Three small changes:
- Some of the tests were relying on a barrier to ensure that all tasks had started before any proceeded.  This resulted in a long delay while the thread pool ramped up slowly to having the desired number of threads.  I put in place a little hack to force it to quickly ramp up.
- Some of the tests were explicitly waiting for 1 seconds.  I lowered that to 0.01 seconds.  This is an example of it not being clear why the delay exists at all, but regardless, this shaves off a lot of time.
- ~25 of the TestFor_Boundary [InlineData]s were specifying a very high workload count that was resulting in each of them taking 6-8 seconds to run.  This is unnecessary, as it's of little value to the testing to have a delegate just chewing up CPU for long periods of time.  I've simply deleted them.

- Our closing the socket may trigger our own pending receive to return successfully with 0 bytes read, as if the other end had closed the connection.  We need to treat this as an ObjectDisposedException to match the Windows behavior.
- If the Socket ends with an operation canceled code, we should throw an OperationCanceledException to match the Windows behavior.
- When using wss (https), we use an SslStream, and if the underlying stream is disposed of, SslStream may throw an InvalidOperationException due to the connection no longer being authenticated.  That needs to be translated into the appropriate exception type to match Windows behavior.

Fix stream disposal causing test failures

Two issues, one preexisting this change and one introduced by it.
- Preexisting: TcpClient on Unix simulates socket.Connect(string host, int port) by creating a new Socket for each possible address we're attempting to connect to.  As a result, if the TcpClient is Dispose'd before the connection is successful, we won't yet have stored the actual Socket into the TcpClient and we won't end up Dispose'ing the Socket.  Then subsequent attempts to send/receive on that socket will continue, as they will be operating on a valid Socket.
- New: Previously the Socket would end up being Dispose'd of when we Dispose'd of the TcpClient we were holding on to.  now that Dispose happens via the NetworkStream.  But we weren't passing ownsSocket: true to the NetworkStream, so when it was Dispose'd, it wasn't Dispose'ing of the Socket, resulting in similar hangs when trying to send/receive in abort scenarios.

Optimize SendFrameAsync to minimize allocations

The previous commit was beneficial in avoiding one large set of overhead, but it also has a flaw that, due to a current behavior in Sockets, sending to a socket inevitably completes asynchronously, which means SendFrameAsync almost always hits an await that yields.  Since this is a very important code path, until the Socket issue can be addressed, we can optimize the common case to minimize the costs involved.

They currently take around ~40s on my laptop.  We can easily reduce this significantly by splitting the single test class into multiple test classes, allowing the default xunit parallelism to run them with more concurrency.  On my quad-core, such that xunit by default allows four tests to run concurrently, the tests now take ~10s.  This commit moves some of the shared logic into a base class, and then essentially replaces the regions with classes.  No test logic was changed at all.

We'll keep this as one method collection to keep the usability benefit it already has (a self-contained piece without dependencies.)

This PR handles the file rename only (so we can track the change more easily.)

Next PR will do the namespace/type rename.

Avoid send/receive delegate allocations with SocketAsyncEventArgs on Unix

Every send/receive operation on a Socket on Unix when using SocketAsyncEventArgs is allocating a new delegate.  Since the whole point of SocketAsyncEventArgs is to cache state and ammortize the costs of things across multiple operations, it's better to create the delegate once and reuse it for all operations.
