Add support for aliases on netcore+Windows

[David-Engel]

This brings support for aliases on netcore+Windows. It also merges TdsParserStaticMethods.cs into common code.

Functionally, this should bring alias support to netcore and netstandard when running on Windows.

[David-Engel]

This diff is a bit misleading. This "deleted" section simply moved down and the NetLib code moved up so that the NetLib code is available on netcore.

I chose the netcore implementation of GetCurrentProcessIdForTdsLoginOnly over the netfx one that relied on the native method. I don't believe it will cause any noticeable behavior differences on netfx.

I chose the netcore implementation of GetCurrentThreadIdForTdsLoginOnly over the netfx one that relied on the deprecated method. I don't believe it will cause any noticeable behavior differences on netfx.

[David-Engel]

I chose a merger of the netfx and netcore implementations of GetNetworkPhysicalAddressForTdsLoginOnly. Netcore had the optimization of caching s_nicAddress but did not have the registry lookup when running on Windows. Since this introduces registry lookups when on Windows, we can bring that functionality to netcore since users generally expect behavior parity when migrating from netfx to netcore.

All the test runs were skipped because the CanCreateAliases didn't return true.
