Add target "slru" to pg_stat_reset_shared()
Currently, pg_stat_reset_shared() cannot reset the counters in the view
pg_stat_slru even if it is a type of shared stats. This patch adds
support for a new value in pg_stat_reset_shared(), called "slru", able
to do that. Note that pg_stat_reset_shared(NULL) also resets SLRU
counters.
There may be a point in removing pg_stat_reset_slru() that was
introduced in 28cac71bd368 (v13~) as the new option overlaps with this
function, but we would lose the ability to reset individual SLRU
counters. This is left for future reconsideration.
