resourcemanager: importance based resource reclaim
Extend the reclaim policy by implementing codec importance
based resource reclaim.
User (of the codec) will assign codec importance to
distinguish important codecs from less important.
Upon resource conflict, the Resource Manager Service
reclaims a codec with the lowest importance (lower than that of
the requesting codec) from the same process (if there is one).
