1. [MLIR][OpenMP] Remove omp.parallel from loop wrapper operations …

   This patch removes the `LoopWrapperInterface` from `omp.parallel` and updates
   the semantics of the interface to make loop wrapper restrictions mandatory to
   operations that have it, rather than a role they might optionally take.
   
   MLIR operation verifiers are updated to expect the "hoisted omp.parallel"
   representation for `distribute parallel do`, to be later implemented in place
   of a loop wrapper `omp.parallel`.

2. [Flang][OpenMP] Re-implement lowering of 'DISTRIBUTE PARALLEL DO' …

   This patch updates the Flang lowering process for `distribute parallel do` to
   follow the "hoisted `omp.parallel`" representation. Now temporary allocations
   produced while lowering the loop body reside inside of that operation instead
   of the loop wrappers' parent region.
   
   Special handling of `omp.parallel` with regards to alloca creation is removed,
   as it's no longer necessary to make this distinction. Impacted Lit tests are
   updated according to the new representation.
