[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 add
mapper_map_always_from.c showing the current (pre-propagation) ALWAYS behavior
(s.y = 0), which the ALWAYS/DELETE/CLOSE propagation PR flips to s.y = 111.

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).

Update offload mapper_map_always_from.c to its now-correct behavior: ALWAYS
forces a member copy-back that the ref count would otherwise suppress, so s.y
reads back as 111 (it was 0 before this change).
