Support setting flow control limits for individual stream types

[rzikm]

Closes #3897.

Description

This PR adds 3 new QUIC_SETTINGS members:

• StreamRecvWindowBidiLocalDefault
• StreamRecvWindowBidiRemoteDefault
• StreamRecvWindowUnidiDefault

With the semantic that if those are set, then they overwrite the StreamRecvWindowDefault setting.

This should preserve backwards compatibility since StreamRecvWindowDefault setting still has effect, but new apps can use the new settings to specify more granular limits.

Testing

Tests in SettingsTests.cpp were updated. I will also verify the change once I managed to write a test app against it.

Documentation

Documentation files were updated.

We need to add a new test case on top of MsQuic API to make sure things work as expected.
