Added several layout renders for NLog.Web.AspNetCore

[bakgerman]

• Do Not Track
• TLS Provider and Referrer Tokens
• • This finishes the TLS renders since we already do TLS Handshake and Client Certificate. I could not find Server Certificate anywhere in HttpContext
• Compression Mode
• Request Trailers and Response Trailers, we did think at first this was for middleware only but after I read about it the application code can set these for http/1.1 chunk and for http/2
• SignalR renders
• • http transport type
• • is 2 way communication capable
• • is connection kept alive

Thank you again for a nice contribution. With unit-tests that provides 100 pct code-coverage. Excellent job.

@bakgerman I was thinking to release NLog.Web.AspNetCore v5.1.0, unless you are already preparing more contributions?

[bakgerman]

I think that sounds great.
