feat: Add new span attributes to more closely match OTel spec

[chynesNR]

This was trickier than first expected for a few reasons:

• For database calls, we want the port, but what we store is the "port, path, or ID" and we don't record which it is. I had to split out the port at creation time.
• The "known values" for database providers that OTel uses are close to, but not exactly the same as, the ones we use
• The request for managed Thread ID doesn't really align with the way .NET handles async work. For now at least, we'll only provide the Thread ID if all Segments occur on the same thread.
• Both database calls and HTTP requests now have server.address and server.port attributes, but they're optional for database calls (making them Agent attributes) and required for HTTP requests (making them Intrinsic attributes)

Resolves #1942
