[MLIR][SCFToOpenMP] Fix crash when lowering vector reductions (#173978) ...

This patch fixes a crash in the SCF to OpenMP conversion pass when
encountering scf.parallel with vector reductions.

- Extracts scalar element types for bitwidth calculations.
- Uses DenseElementsAttr for vector splat initializers.
- Bypasses llvm.atomicrmw for vector types (not supported in LLVM IR).

Fixes #173860
