[CUDA][HIP] Reorganize options for documentation

[yaxunl]

Summary

Reorganize options and group them as "Common Offloading flags", "CUDA flags" and "HIP flags", so that they will be grouped together like "OpenCL flags" and "SYCL flags" in https://clang.llvm.org/docs/ClangCommandLineReference.html

[jhuber6]

I think this is good, there's been some confusion around which ones goes to what.

clang/include/clang/Driver/Options.td

1021

Can you fix this copy paste error while you're here?

The existing flags uses are misnomer (Flag does not accept values). Perhaps use options for new option groups.

[yaxunl]

clang/include/clang/Driver/Options.td

155

will do

It has been fixed in the trunk.
