[ROCm][Windows] Run hipcc with compatibility flags. (#153986)

Browse Source 
See also https://github.com/ROCm/TheRock/issues/590. Including the `-Wno-ignored-attributes` flag here avoids 700MB of log warning spam while compiling and the `-fms-extensions` seems beneficial to include: https://clang.llvm.org/docs/MSVCCompatibility.html.
