clang/win: Let SK_TRACEHR not produce -Wunused-value warnings in release builds.

Fixes warnings like:
..\..\third_party\skia\include\utils\win\SkHRESULT.h(51,23) :  note: expanded from macro 'HRNM'
                      ^~~~~~~~~~~~~~~~~~~~~~~~~
..\..\third_party\skia\include\utils\win\SkHRESULT.h(26,20) :  note: expanded from macro 'HR_GENERAL'
        SK_TRACEHR(_hr, _msg);\
                   ^~~
..\..\third_party\skia\include\utils\win\SkHRESULT.h(20,31) :  note: expanded from macro 'SK_TRACEHR'
                              ^~~
