  [MLIR][OpenMP] Make omp.simdloop into a loop wrapper

This patch updates the definition of `omp.simdloop` to enforce the restrictions
of a wrapper operation. It has been renamed to `omp.simd`, to better reflect
the naming used in the spec.

Some changes to Flang lowering and OpenMP to LLVM IR translation are introduced
in order for this patch to be able to compile and run. The eventual long term
solution might be different.

This is a WIP posted early for visibility. Related unit tests need updating and
there might still be some bugs due to lack of testing.
