* Improved server logging to include S.N.Quic traces as well.

* MsQuicBuffers copy given memory into native instead of pinning

* Process incoming frames before sending frames for Http2Connection.

Moves the ProcessIncomingFramesAsync method before sending the preface.
This fixes a deadlock when using a NamedPipe as a transport where
incoming frames need to be read before being able to write.
Also rename _expectingSettingsAck to _receivedSettingsAck to clearly
specify that the settings frame has being received.

Fix #73097

* Addressed PR Feedback.

Added test that will prevent regresions when using Http2 with NamedPipe as a transport.

* More reliably clean up more SafeHandle instances

This calls Dispose on SafeHandles (or things wrapping SafeHandles) that were otherwise being left for finalization:
1. Some of these are fixing finalization happening even on success paths (typically where the implementation isn't disposing of something that directly or indirectly wraps a SafeHandle).
2. Some of these are fixing finalization happening for invalid SafeHandles.
3. Some of these are fixing tests to finalize less.  My goal with fixing the tests was to eliminate the noise in order to find instances of the other two cases.

These were found primarily via two means:
- Debug-instrumentation in SafeHandle to log when one is finalized.  This instrumentation is built into debug/checked builds of SafeHandle and requires setting the DEBUG_SAFEHANDLE_FINALIZATION environment variable to "1".
- Auditing use of SafeHandle.IsInvalid

There's a lot more that can be cleaned up using the SafeHandle instrumentation, but I'm pausing here for now.  The System.IO.Pipes, System.IO.FileSystem, and System.Security.Cryptography tests are clean on Windows.
