dev-util/hip: get rid of FindHIP and keep hip-config.

According to the cmake documentation, do not write find modules for
packages that themselves build with CMake. Instead provide a CMake
package configuration file with the package itself.

FindHIP is needed by HIP over CUDA, not what Gentoo is aiming for.
