* Cleanup UTF8Encoding tests

- Fix a bunch of tests that didn't actually test anything. They just
called the method without any assertions or checks after.
- Rename tests to follow guidelines, instead of "PosTest1" and
"NegTest2"
- Take advantage of xunit
- Shorten tests by using quicker and newer code
- Use EncodingTestHelpers

Our code coverage run doesn't currently employ /p:TestWithLocalLibraries=true.  While that's good for the common need of understanding how tests for a particular library are exercising that library, it would also be good to be able to understand how the libraries are exercised by any tests and other libraries in the repo.  This commit adds an additional such job.
