BZLZHH b9a15aed61 [Feat] (DirectVulkan, MG_Impl): GPU transform feedback primitive queries
The TF primitive queries now ride VK_QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT
pools when the device reports transformFeedbackQueries: each captured draw
is wrapped in a slot (shared between both GL targets when active
together), and results sum the (written, needed) pairs -
GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN from the first,
GL_PRIMITIVES_GENERATED from the second. This is exact through geometry
shaders, so KHR-GL33.transform_feedback.query_geometry_* pass; the CPU
accounting delta remains the fallback for backends without the feature.
