Intrinsics__is_layout_compatible and__is_pointer_interconvertible_base_of are implemented in Clang 19 (LLVM-81506,LLVM-88473), so this PR unblocks the corresponding standard library components for Clang.

Unfortunately, according toWG21-P0466R5,

  • __cpp_lib_is_layout_compatible coversis_layout_compatible(_v) and__is_corresponding_member, and
  • __cpp_lib_is_pointer_interconvertible coversis_pointer_interconvertible_base_of(_v) andis_pointer_interconvertible_with_class,

so no feature-test macro should be unblocked for Clang at this moment.

Also adds workaround forLLVM-135273 and RWC, and specially handles EDG for IntelliSense with LLVM toolset.
