* Implement `rocshmem_ptr` in IPC conduit
* tests: add functional test for `rocshmem_ptr`
- Add safety check for pointer access and condition check before printing results for `rocshmem_ptr` test
- Use `rocshmem_put` to store `rocshmem_ptr` availability for data validation
* rocshmem_config.h needs to be in a similar directory structure for
includes to work when building testers in build, and from an installed
library
* Do not change installed rocshmem.hpp
* Refactor `Barrier_all` and `Sync_all` to use default context
- Removed context-specific implementations of barrier_all and sync_all
- Added barrier_all and sync_all to the default context implementation
- Updated functional tests to use the default context for barrier_all and sync_all
* Update `Barrier_all` and `Sync_all` API usage in documentation
* Update `CHANGELOG`

* Fix deadlock in `rocshmem_ctx_wg_barrier_all` API in IPC conduit by adding per-context pSync buffers and context IDs
- Added separate pSync buffers for each device context
- Resolved deadlock when invoking barrier API (`rocshmem_ctx_wg_barrier_all`) concurrently from multiple contexts
* Update barrier_all functional tests for multi-context support
* Add thread, wavefront, and workgroup-level barrier_all APIs in IPC and RO conduits
- Implemented barrier_all APIs at thread, wavefront, and workgroup granularity
- Added support in both IPC and RO conduits
- Updated functional tests to cover all `barrier_all` APIs
* Add thread, wavefront, and workgroup-level sync_all APIs in IPC and RO conduits
- Implemented sync_all APIs for thread, wavefront, and workgroup scopes
- Added support into both IPC and RO conduits
- Added functional tests to cover all `sync_all` APIs
* Add interanl put_mem/get_mem{_wave, _wg} functions to read/write to work/sync arrays
* Add condition check to ensure all MPI processes are on the same compute node for IPC conduit
* Update roc_shmem_ctx_fence API to use team-relative PE numbering
* Update backend to populate team_opaque member of ROC_SHMEM_CTX_DEFAULT (used to store information about the team wrt TEAM_WORLD)
code is based on the GPUIB implementations of the routines, which seem
however generic enough to work also for the IPC conduit.
Some code is in for broadcast, fcollect, and alltoall.
* add backend_ipc.{cpp & hpp}
* rename context_ipc.{cpp & hpp} to context_ipc_device.{cpp & hpp}
* add host interface to IPC backend
* add context_ipc_host.{cpp & hpp} to support host interface
* add USE_RO compile flag to enable support for single backend interface at a time
* add ipc_single script to build rocSHMEM with IPC backend
