kvserver: default PriorityInversionRequeue to true

Previously, we introduced PriorityInversionRequeue to handle cases where a range
is enqueued with a high-priority action but computes a lower-priority action at
processing, re-adding the range with its updated priority. We plan to backport
this setting soon. To allow some bake time, we enable it on true in master,
while the backport will include only the previous PR with the default value set
to false.
