[UR][L0v2] remove comment leftovers and fix testing macro (#21089)
fix UUR_DEVICE_TEST_SUITE_WITH_QUEUE_TYPES_AND_PARAM
At this moment, this macro is not used in any tests. The helper is
provided for future test extensions.
Example usage:
```
UUR_DEVICE_TEST_SUITE_WITH_QUEUE_TYPES_AND_PARAM(
urEnqueueMemBufferFillTest,
testing::ValuesIn(test_cases),
::testing::Values(UR_QUEUE_FLAG_OUT_OF_ORDER_EXEC_MODE_ENABLE,
UR_QUEUE_FLAG_SUBMISSION_IMMEDIATE),
uur::printFillTestStringMultiQueueType<urEnqueueMemBufferFillTest>);
```
