dev-util/hip: C++ Heterogeneous-Compute Interface for Portability.

This ebuild is adopted from that of https://github.com/justxi/rocm.

1. change hip location from /usr/lib/hip/<ver> to /usr/lib/hip. We do
   not have plans to support multiple hip versions at once.

2. turn the hipify function off as it does not work.  We will
   re-enable it as a USE flag when possible.

3. properly prefixify the source code making use of hprefixify().

4. migrate from cmake-utils to cmake eclass.

Closes: https://github.com/gentoo/gentoo/pull/18787
