[PATCH i-g-t] tests/amdgpu: Add user queue test control via environment variable

[Jesse.Zhang]

- Add environment variable check 'AMDGPU_DISABLE_USERQTEST' to control
  user queue test execution
- Only run SDMA with UMQ test when both enabled via the flag and
  hardware supports it (userq_arr_cap[AMD_IP_DMA])
- Helps disable user queue tests when needed while keeping other tests
  active
