[SYCL][UR][L0 v2] fix urQueueCreateWithNativeHandle (#17784)

getSignalEvent in ur_command_list_manager returned nullptr when queue
was not set. This was the case when initializing the command list
manager in queue ctor called from urQueueCreateWithNativeHandle.

Fix this by passing queue to the command list manager and removing the
default nullptr value from the ctor (to avoid this issue in future).

Also, even if queue is nullptr, return the event instead of nullptr from
getSignalEvent. This event is mostly functional, it just cannot be used
for profiling.
