This patch separates the lowering dispatch for host and target devices. For the target device, if the current operation is not a top-level operation (e.g. omp.target) or is inside a target device code region it will be ignored, since it belongs to the host code. This is an alternative approach to #84611, the new test in this PR was taken from there.
