[flang][OpenMP] Lower allocate clauses for scalar parallel privates

Lower OpenMP `allocate` clauses on `parallel` constructs for fixed-size
intrinsic scalar `private` and `firstprivate` variables.

Flang records the private operand associated with each allocate item.
The OpenMP dialect verifies this mapping, and LLVM IR translation uses
the runtime-allocated pointer as the private storage and releases each
pointer with its corresponding allocator during region finalization.

This preserves one-time evaluation of allocator expressions and cleanup
on normal and cancellation paths. Unsupported types, device lowering,
other clause-bearing operations, and the `align` modifier remain
unsupported.

Tests cover source lowering, dialect verification and attribute
preservation, allocator identity, reverse-order cleanup, privatizer
deallocation, and cancellation.
