[lldb][NFC] Rename ClangASTContext to TypeSystemClang
Summary:
This commit renames ClangASTContext to TypeSystemClang to better reflect what this class is actually supposed to do
(implement the TypeSystem interface for Clang). It also gets rid of the very confusing situation that we have both a
`clang::ASTContext` and a `ClangASTContext` in clang (which sometimes causes Clang people to think I'm fiddling
with Clang's ASTContext when I'm actually just doing LLDB work).
I also have plans to potentially have multiple clang::ASTContext instances associated with one ClangASTContext so
the ASTContext naming will then become even more confusing to people.

unittests: Use yaml2obj as a library instead of an external process
Summary:
Recently, yaml2obj has been turned into a library. This means we can use
it from our unit tests directly, instead of shelling out to an external
process. This patch does just that.
