[OpenMP][test] Address review: restructure present-check mapper tests

Move the present-check pointee tests into this PR (PR1) with RUN lines and
FIXME/EXPECTED comments matching the current pre-feature behavior, per review:
  - mapper_map_present_ptee.c
  - mapper_map_mbr_ptee_then_present_mbr_ptee.c
  - mapper_map_mbr_then_present_mbr_ptee.c
Later PRs update these checks as the behavior becomes correct.

Also:
  - mapper_map_ptee_then_present_absent_mbr.c: reword the FIXME to just say
    PRESENT should be propagated to the s.x member entry (drop the PTR_AND_OBJ
    wording, which belongs in the propagation PR).
  - mapper_target_update_present_ptee.c: add OOB CHECK/EXPECTED lines and a
    subset-transfer FIXME; use fprintf consistently.
  - target_map_nested_ptr_member_mapper_codegen.cpp: add the OpenMP 6.0 RUN
    line now (CHECK-60 currently identical to CHECK, with a FIXME) so the
    propagation PR only needs to flip the pointee map-type values.

[OpenMP] Propagate ALWAYS/DELETE/CLOSE map-type modifiers to mapper entries

When a map clause uses a user-defined mapper, the map-type-modifying bits
(ALWAYS, DELETE, CLOSE) on the outer clause must apply to each map the mapper
inserts (OpenMP 6.0:281:34). Propagate them in emitUserDefinedMapper by OR-ing
the imported modifier bits into each pushed component, except ATTACH entries
(ATTACH|ALWAYS is reserved for attach(always) and the other bits are
meaningless for ATTACH).

PRESENT is intentionally not propagated here yet (a TODO notes it is handled in
a follow-on, since it requires distinguishing pointee entries from the struct's
own storage).

Add offload mapper_map_always_from.c: ALWAYS forces a member copy-back that the
ref count would otherwise suppress.

Git commit 9b175e28e59b07bdb185eab2275c504e2f8a9236 by Abhinav Gaba on 24/07/2026 at 20:37..
[OpenMP][Clang] Enable ATTACH-style maps for mappers.

Track per-entry attach-ptr info (HasAttachPtr) through mapper codegen so that
emitUserDefinedMapper does not add a new outer MEMBER_OF to pointee/combined
entries (which occupy different storage than the struct) or to ATTACH entries.
Clang and the MLIR translator populate the per-entry array in parallel with the
other MapInfosTy arrays.

Address review:
  - Rename MapSkipMemberOfArrayTy to MapHasAttachPtrArrayTy to match the
    HasAttachPtr field it backs.
  - Restructure the emitUserDefinedMapper comment into a bulleted (*)/(**)/(***)
    list keyed to the example entries.
  - Reword the Clang comments: HasAttachPtr marks pointee entries that have a
    base attach-ptr; a combined entry has a base attach-ptr if its constituents
    do; cross-reference emitUserDefinedMapper for the MEMBER_OF rationale.
  - Update the moved present-check tests to their now-correct behavior (the
    attach-style maps make the inbounds present checks pass and remove the
    "explicit extension" errors).
