[PATCH i-g-t v2 2/2] lib/amdgpu: Implement priority and secure flags for user queues

["Jesse.zhang@amd.com" <jesse.zhang@amd.com>]

This patch adds support for queue priority levels and secure queue
creation flags in the user queue interface. The changes include:

1. Extended the amdgpu_ring_context struct to store queue priority

2. Modified amdgpu_user_queue_create() to:
   - Parse and pass through priority flags from context
   - Handle secure queue flag
   - Include flags in queue creation IOCTL calls

The priority levels allow workloads to specify different scheduling
priorities, with HIGH priority restricted to admin-only use. The secure
flag enables creation of queues that can access protected content.

This matches the corresponding libdrm changes in commit fdf384d4b546
("amdgpu: add priority and secure flags for user queues").
