* Update the naming convention for collective APIs to ensure consistency across the interface.
* Move all collective API declarations to rocshmem_COLL.hpp
* The following APIs were updated as part of this change:
- `barrier`
- `barrier_all`
- `sync`
- `sync_all`
- `all_to_all`
- `broadcast`
- `fcollect`
- `all_reduce`
* Update header file generation code for collective APIs
[ROCm/rocshmem commit: 68421895d6]
* Add thread, wavefront, and workgroup-level `barrier` APIs in IPC and RO conduits; remove collectives on default context
- Implemented `barrier` APIs for thread, wavefront, and workgroup scopes
- Added support into both IPC and RO conduits
- Added functional tests to cover all `barrier` APIs
- Removed collective operations on default context
* Add thread, wavefront, and workgroup-level `sync` APIs in IPC and RO conduits.
- Implemented `sync` APIs for thread, wavefront, and workgroup scopes
- Added support into both IPC and RO conduits
- Added functional tests to cover all `sync` APIs
* update naming convention for context-based `barrier` APIs
[ROCm/rocshmem commit: dc61bca066]
* add team-barrier implementation
add a team-barrier API and implementation in the IPC and RO conduit.
Clean up some of the logic in the RO Conduit to distinguish between
sync, sync_all, barrier, and barrier_all.
* add team_barrier_tests to functional tests
