[TransferEngine] Rename comm_group, convert SetAccess id, reserve A3 at 78TB (#3481)

create_shared_segment's process group is not intrinsically TP; keep
tp_group as a deprecated alias. Convert user device id to driver
logical id before MemSetAccess, and start A3 NoUCMemory at 78TB past
HIXL's default [40TB, 72TB) fabric window.
