Add Span/Memory overrides to StreamWriter (dotnet/corefx#24725)

- Refactors StreamWriter to work in terms of Span/Memory.
- Adds TextWriter-overrides for the Span/Memory-based methods.
- Exposes the new members from the ref.
- Adds tests for the new methods.
- Respond to API review feedback that we should be naming parameters to match existing overloads, here using `buffer` instead of `source` or `destination`, since `buffer` is already used in overloads on these types.

Update places to compare file names and not paths

There is an msbuild issue https://github.com/Microsoft/msbuild/issues/2620
that causes some paths to normalized where they weren't before and
this normalization causes conditions to start changing and excludes to fail.

In general it is not a good idea to depend on path comparision as a string
anyway so switched to using the file name in a few places instead of path.

Fix HttpWebRequest when sending with HTTP/1.0 (dotnet/corefx#24644)

* Fix HttpWebRequest when sending with HTTP/1.0

The HttpWebRequest.ProtocolVersion property was implemented. But it was
not checked when actually creating the request (which uses HttpClient
underneath). So, all requests were sent with HTTP/1.1.

This fix now uses the ProtocolVersion property and sends either
HTTP/1.0 or HTTP/1.1.

Note: HTTP/2.0 is currently not supported when setting the
ProtocolVersion property. An ArgumentException is thrown. This is the
existing .NET Framework behavior which was ported to .NET Core. We could
investigate changing this in the future to allow ProtocolVersion to be
set to 2.0.
