[SYCL][HIP] Port HIP plugin to Unified Runtime (#9617)

This moves the HIP plugin implementation to Unified Runtime; and changes
the pi_hip plugin to use pi2ur to implement PI. The changes to the
implementation have been kept to a minimum and should be functionally
the same. Documentation and comments have been moved verbatim, other
than changing PI references to UR.

This PR is based on top of the CUDA adapter
(#9512) so will only be ready when
that is merged.
