Subject: dev-util/hip: replace hcc with rocclr.

hcc is deprecated and rocclr is the mainstream.  Replace remaining hcc
in run_hipcc.cmake and hipcc.  This also enables --genco support, which
will be essential in building e.g. Tensile.

Fix trailing - in HIP_LIB_VERSION_STRING by imposing Gentoo version.

Let cmake use the correct HIP_CLANG_INCLUDE_PATH for llvm-roc.

Closes: https://bugs.gentoo.org/733794
Package-Manager: Portage-3.0.12, Repoman-3.0.1
