SWDEV-264220 - Provide CMake hip language configuration information

This provides the required information for CMake to bootstrap HIP language and runtime support. In particular this file is consumed by CMake during HIP compiler detection to determine the required flags needed for compilation and linking. Initial design was discussed in #2158 Add copyright / license header Change-Id: I10acb860bf6291b2deb6b678e6e916faa7c82c2a [ROCm/hip commit: 8c90ab196b]
