[SYCL][UR] Add UR_QUEUE_INFO_EMPTY support for OpenCL (#19151)
To fix CTS test
(https://github.com/KhronosGroup/SYCL-CTS/blob/b5cf985ecc497f82045165e9309fdc7a990c7e60/tests/extension/khr_queue_empty_query/queue_empty.cpp)
failures for the `sycl_khr_queue_empty_query` extension (implemented in
https://github.com/intel/llvm/pull/18799), which are caused by the error
`UR_RESULT_ERROR_UNSUPPORTED_ENUMERATION` emitted in the old code.
