estewart08 0e7262407c [offload] - Remove standalone build in favor of 'runtimes' (#170693) ...

Summary:
Follow up on removal of OPENMP_STANDALONE_BUILD in openmp (#149878).
This
build method is redundant and can be accomplished via runtimes.

Removes support for:
`cmake -S <llvm-project>/offload ...`

 Switches over to:
`make -S <llvm-project>/runtimes -DLLVM_ENABLE_RUNTIMES=openmp;offload
...`

Libomptarget has a dependency on libomp.so and requires the omp cmake
target to exist at build time, which is why both runtimes are listed.

Updates cmake compiler logic in offload/CMakeLists.txt to mirror openmp
changes:
 [openmp] Allow testing OpenMP without a full clang build tree (#182470)

User will still need to have a separate invocation to build openmp
DeviceRTL via:
`-DLLVM_ENABLE_RUNTIMES=openmp`
`-DLLVM_DEFAULT_TARGET_TRIPLE=<amdgcn-amd-amdhsa|nvptx64-nvidia-cuda>`
