[HIP] Add option --gpu-max-threads-per-block=n Add this option to change the default launch bounds. Differential Revision: https://reviews.llvm.org/D71221

[HIP] Fix duplicate clang -cc1 options on MSVC toolchain HIPToolChain::TranslateArgs call TranslateArgs of host toolchain with the input args to get a list of derived args called DAL, then go through the input args by itself and append them to DAL. This assumes that the host toolchain should not append any unchanged args to DAL, otherwise there will be duplicates since HIPToolChain will append it again. This works for GNU toolchain since it returns an empty list for DAL. However, MSVC toolchain will append unchanged args to DAL, which causes duplicate args. This patch let MSVC toolchain not append unchanged args for HIP offloading kind, which fixes this issue. Differential Revision: https://reviews.llvm.org/D76032
