[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).
