Add '--hip-clang-launch' to favor <<<>>>-based launch. (#17686)
Summary:
hip-clang uses triple chevron kernel dispatch syntax. Add an option to the hipification script to skip translating triple chevron to hipLaunchKernelGGL.
Once we switch to hip-clang, this option will be default and subsequently removed.
