xfs: make for_each_perag... a first class citizen
for_each_perag_tag() is defined in xfs_icache.c for local use. Promote this to xfs_ag.h and define equivalent iteration functions so that we can use them to iterate AGs instead to replace open coded perag walks and perag lookups. We also convert as many of the straight forward open coded AG walks to use these iterators as possible. Anything that is not a direct conversion to an iterator is ignored and will be updated in future commits.
