On modern system e.g. render nodes are made accessible via the udev
uaccess functionality, which adds the logged in user to the ACL of the
device. This means just checking for user and group is bound to give
false positives. Instead use os.access as a first check

This enhances libhsakmt's capabilities for multi-context KFD support by implementing per-context topology management.
Changes:
* Add hsaKmtGetClockCountersCtx for multi-context support
- Add context-aware version of hsaKmtGetClockCounters
- Original API is retained as a wrapper calling the ctx-version with primary context
* Enable independent debug sessions across multiple KFD contexts
-Create hsa_kfd_debug_context, introduce context-aware debug APIs, shift debug state to per-context
* Add perf sub-context for per-context performance counter management
- Introduce hsa_kfd_perf_context, move counter properties, add context - aware perf APIs, and update initialization
* Refactor FMM for per-context resource management
- Refactor multiple global variables related to FMM, including
GPU ID arrays , svm, cpuvm_aperture, and mem_handle_aperture to hsa_kfd_fmm_context
* Implement per-context topology for complete context isolation
- Migrate global topology data (g_system, g_props, map_user_to_sysfs_node_id)
to per-context hsa_kfd_topology_context structure
- Update all topology functions to accept HsaKFDContext parameter for
context-aware operations (validate_nodeid, get_node_props, get_iolink_props, etc.)
- Refactor topology snapshot management for per-context isolation
- Add context-aware PMC trace access APIs
