Add __counted_by() annotations to flexible array members: - hfi_capabilities::data, counted by num_capabilities - hfi_profile_level_supported::profile_level, counted by profile_count - hfi_resource_ocmem_requirement_info::requirements, counted by num_entries
This improves run-time bounds checking via CONFIG_UBSAN_BOUNDS and compile-time object size resolution via __builtin_dynamic_object_size().
