Update Barrier and Sync APIs (#73)

* 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
