Subject: score: add Inherited_priorities priority queue and functions

Adds enqueue, dequeue, requeue, evaluate, and release functions
for the thread priority node priority queue of inherited priorities.
Add calls to these functions as needed to maintain the priority
queue due to blocking, unblocking, and priority changes.

Closes #3359.
