Fix for issue 46942. VSIX suppressors do not run when Nuget analyzers / suppressors are installed.

Previously we tried this by simply parsing the string as XML, and if
that succeeded great; otherwise we'd catch the first-chance exception
and then treat it as a regular file. This is problematic if you intend
for your test to be using XML, but you have some typo that prevents it
from parsing properly; in that case the fallback of a single file
with the XML as contents may result in tests incorrectly passing if
the compiler succeeds in producing a valid enough tree. It's also then
makes the XML error easy to understand since you'll get the parse error.
