  -----------
  [Flang][MLIR][OpenMP] Use function-attached target attributes for OpenMP lowering

This patch removes the `omp.target` module attribute, since the information it
held on the target CPU and features is available through the `fir.target_cpu`
and `fir.target_features` module attributes. Target outlining during the MLIR
to LLVM IR translation stage is updated, so that these attributes, at that
point available as `llvm.func` attributes, are passed along to the newly
created function.
