freedreno: add support for hw accumulating queries

Some queries on a4xx and all queries on a5xx can do result accumulation
on CP so we don't need to track per-tile samples.  We do still need to
handle pausing/resuming while switching batches (in case the query is
active over multiple draws which are executed out of order).

So introduce new accumulated-query helpers for these sorts of queries,
since it doesn't really fit in cleanly with the original query infra-
structure.
