[Sema] Handle transparent_union attributes in C mode only
This commit marks the transparent_union attributes as C only because clang
doesn't support them in C++ mode. Prior to this commit, clang still tried to
verify these attributes in C++, leading to crashes when analyzing templated
transparent_union unions that have dependent field types. This commit ensures
that such crashes won't happen again.
As a result of this commit clang now displays a warning every time it encounters
a transparent_union attribute in C++ mode.
