  Log Message:
  -----------
  [flang][OpenMP] Lower align modifiers on allocate clauses (#211624)

Closes #211620.

Stacked on #211621.

This adds `align` modifier lowering to the host `omp.parallel` path
introduced by the parent change. It carries and verifies per-item
alignment metadata and uses aligned runtime allocation when alignment is
specified, while retaining the unaligned path otherwise.

Other clause-bearing constructs and unsupported data types remain out of
scope.
