[SYCL][DOC] Remove size, get_wait_list from queue (#7612)

Remove the `queue::size` and `queue::get_wait_list` member functions
from the proposed "sycl_ext_oneapi_queue_status_query" extension. After
some implementation experience, we learned that these functions cause
some unexpected overhead. Since we only have a strong use case for
`queue::empty`, we decided to remove these others.

Also rename the extension to match the new scope.
