Pack AFBC resources asynchronously in order to prevent stalls at texture upload waiting for 1) the AFBC staging blit (sparse encoding) to complete and 2) the AFBC payload sizes retrieval. After a texture upload, an AFBC resource is now progressively packed at each read access once consecutively accessed a certain number of times without a write access. This allows to prevent most stalls by making AFBC packing a progressive async background process. A useful side effect is that consecutive glTexSubImage*() calls on the same texture (for texture atlases for instance) don't uselessly respawn packing. A new AFBC-P driconf option "pan_afbcp_reads_threshold" is added to tweak the consecutive reads threshold.
