turnip: Implement VK_EXT_primitives_generated_query 

Similar to pipeline statistics but done for a single counter.

We use REG_A6XX_RBBM_PRIMCTR_7 to get generated primitives
and not PRIMCTR_8 because PRIMCTR_7 counts pre-clipped prims
while PRIMCTR_8 counts them after clipping.

OpenGL spec for GL_PRIMITIVES_GENERATED says:
 "Subsequent rendering will increment the counter once for every
  vertex that is emitted from the geometry shader, or from the
  vertex shader if no geometry shader is present."

Passes tests:
 dEQP-VK.transform_feedback.primitives_generated_query.*
