  [mlir][EmitC] Convert MemRef::DeallocOp (#194591)

Add `memref.dealloc` lowering to EmitC by mapping pointer-backed
deallocations to `void*` cast + `free()` call. This complements the
existing `memref.alloc` lowering to `malloc()` / `aligned_alloc()` and
ensures the pass emits the required standard library include when
`free()` is used.

Assisted-by: Codex (refine implementation + tests). I reviewed all code
and tests before submission.
