[PGO][HIP] Support hipModuleLoad in offload PGO (#211875)

Offload PGO finds profile sections by inspecting the image passed to
hipModuleLoadData. hipModuleLoad only provides a file name, so its
device
profile counters were not collected.

After a successful hipModuleLoad, read the code object with the existing
profile file-buffer helper and register it through the same path used by
in-memory module loads.
