r600g, radeonsi: fix primitives-generated query with disabled streamout
Buffers are disabled by VGT_STRMOUT_BUFFER_CONFIG, but the query only works
if VGT_STRMOUT_CONFIG.STREAMOUT_0_EN is enabled.
This moves VGT_STRMOUT_CONFIG to its own state. The register is set to 1
if either streamout or the primitives-generated query is enabled.
However, the primitives-emitted query is also incremented, so it's disabled
by setting VGT_STRMOUT_BUFFER_SIZE to 0 when there is no buffer bound.
This fixes piglit:
ARB_transform_feedback2/counting with pause
EXT_transform_feedback/primgen-query transform-feedback-disabled
