Provide managed CA and Embedded UI DTF libraries via NuGet

Lots of refactoring to bring the SFX tooling back into the 'dtf'
layer since they are (in the end) tightly coupled to some DTF
assemblies. Also refactored the DTF tests into their own folder
and added a couple integration tests to build using the new CA/UI
NuGet package.

Closes wixtoolset/issues#6080
