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

ScottTodd · 2025-05-20T21:58:34Z

See also ROCm/TheRock#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.
