svga: implement TGSI_PROPERTY_FS_COLOR0_WRITES_ALL_CBUFS
Fixes several colorbuffer tests, including piglit "fbo-drawbuffers-none" for "gl_FragColor" and "glDrawPixels" cases. v2: rework patch to only avoid creating extra shader variants when TGSI_PROPERTY_FS_COLOR0_WRITES_ALL_CBUFS is not specified. Per Jose. Use a write_color0_to_n_cbufs key field to replicate color0 to N color buffers only when N > 0 and WRITES_ALL_CBUFS is set. Reviewed-by: José Fonseca <[email protected]>
