  [offload][runtimes] Forward user-provided system configuration (#96303)

In order for LLVM_ENABLE_RUNTIMES projects to find their requirements,
they need access to user-provided configuration options such as
`CMAKE_PREFIX_PATH`. Forward a selection of configuration options such
that runtimes uses the same system introspection as LLVM and
LLVM_ENABLE_PROJECTS do.

The concrete symptom this is solving is that the path to CUDA is
provided using `cmake -DCUDA_TOOLKIT_ROOT_DIR=/opt/cuda` or `CUDA_PATH`,
but is ignored by offload. Handling for this case already existed for
libc, but only when it was enabled and only `CUDAToolkit_ROOT` (The
former is for `find_package(CUDA)`, the latter for
`find_package(CUDAToolkit)`, `CUDA_PATH` is used by
`find_package(CUDAToolkit)` and `enable_language(CUDA)`).
