- precursor for #129
- remove unused `GeneratorResults` ctor to avoid duplicating `ParserResults` code
nit: make a few `ParserResults` properties immutable
- also change `ParserErrors` type to `IEnumerable<RazorError>`
The largest sub-segment change was removing the Microsoft.TestCommon project. Ultimately it involved touching every test file and re-mapping them to use Xunit directly instead of a helper class which was initially ported over for legacy reasons. Lastly how files were embedded before included the full path to the embedded file; currently there is no path associated with the embedded files so had to make modifications to account for this. This is a temporary change and I left comments in the locations where we'll need to uncomment out old code once embeded files act the same as they used to.
