* Add host APIs for querying device ctx and remote heap pointer * Host API to query device pointer for ROCSHMEM_DEFAULT_CONTEXT, this is needed to support dynamic module initialization via device kernel library bitcode. * Host API to query remote symmetric heap pointer that can be used in custom device kernel for RMA operations. * Added rocshmem_ptr implementation within the Host Context class * Enables pointer retrieval functionality for symmetric data objects * Copy IPC pointers to host memory in RO host context --------- Co-authored-by: avinashkethineedi <avinash.kethineedi@amd.com>
