  [Flang][OpenMP] Refactor loop-related lowering for composite support

This patch splits the lowering for `omp.loop_nest` into its own function and
updates lowering for all supported loop wrappers to stop creating this
operation themselves.

Lowering functions for loop constructs are split into "wrapper" and
"standalone" variants, where the "wrapper" version only creates the specific
operation with nothing inside of it and the "standalone" version calls the
former and also handles clause processing and creates the nested
`omp.loop_nest`.

"Wrapper" lowering functions can be used by "composite" lowering functions in
follow-up patches, minimizing code duplication.

Tests broken as a result of reordering between the processing of the loop
wrapper's and the nested `omp.loop_nest`'s clauses are also updated.
