  [mlir] Use hip's config mode to find libraries

Instead of using find_package(HIP) to find FindHIP.cmake, which
doesn't seem to be the preferred way to find HIP anymore, use
find_package(hip CONFIG) to find the HIP configuration. Give
preference to ${ROCM_PATH} over ${ROCM_PATH}/hip in order to handle
the fact that newer ROCm versions prefer the include path to use
${ROCM_PATH}/include/hip over ${ROCM_PATH}/hip/innclude/hip (the
latter throws up a bunch of deprecation warnings)

Then, instead of trying to manually find the host-side headers and
runtime library by hand, use the hip::host and hip::amdhip64 libraries
that the config module defines.

This makes the CMake config much less error-prone and brings it in
line with the recommended approach to finding HIP.
