st/nine: Use gallium caps to get if queries are supported. (v2)

Some queries need the driver to advertise a cap to be supported.
For example r300 doesn't support them.

v2 (David): check also for PIPE_CAP_QUERY_PIPELINE_STATISTICS, fix wine
            tests on r300g

st/nine: Queries: Fix D3DISSUE_END behaviour.

Issuing D3DISSUE_END should:
. reset previous queries if possible
. end the query

Previous behaviour wasn't calling end_query for
queries not needing D3DISSUE_BEGIN, no resetting
previous queries.
