Add WCF support for IRequestSessionChannel and IDuplexChannel

[repl-chris]

Fixes #1369

Changes

The provided configuration from the issue uses an IRequestSessionChannel shape, which the instrumentation did not yet support. This PR adds support for IRequestSessionChannel. I've also enabled support for IDuplexChannel shaped channels, since the implementation actually already supported it as part of the IDuplexSessionChannel implementation.

For significant contributions please make sure you have completed the following items:

• Appropriate CHANGELOG.md updated for non-trivial changes
• Design discussion issue #
• Changes in public API reviewed

@repl-chris I just pushed a little bit of refactoring so that we can expose a strongly-typed "Inner" on the base class. That gets rid of the need for [private|protected] new [ChannelType] Inner { get => ([ChannelType])base.Inner; } we had been using in all the derived classes.

Nice....looks good 👍

@repl-chris This looks good to me but before we can merge we need to update the CHANGELOG and perhaps the README with the new supported matrix?
