Reviewed by Eric Carlson.
Both MSE and MediaSourceRemote and RemoteMediaResourceLoader WorkQueue were
created using QOS::Background priority.
Trace shows that when a task is being run on those WorkQueues, they are either
being pre-empted or yielded and sometimes
it takes over 10s for a task to even complete.
We change the priority to the default, the same as what the IPC's WorkQueue is
using.
