Fix include path and wrapper header

Currently std::complex and some other std functions require uses to
include hip_runtime.h before any other headers to work, which is not
reliable.

changes are made in clang to fix this issue:
https://reviews.llvm.org/D81176

which requires hipcc and HIP headers to make corresponding changes.

This patch will make sure the clang change will not break
HIP/ROCclr during this transition.

After the transition is done, we can remove explicitly setting
include path for HIP-Clang and HIP header in hipcc and hip config
cmake files and rely on clang driver to set it automatically.
