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.
