gallium: add PIPE_CAP_QUADS_FOLLOW_PROVOKING_VERTEX_CONVENTION
Just let the hardware do it if it can and avoid drivers having to check for the special case on each draw call. v2: update the draw module

Whether the first vertex should be the provoking vertex, for most primitives.
If not set, the last vertex is the provoking vertex.
-There are several important exceptions to the specification of this rule.
+There are a few important exceptions to the specification of this rule.
* ``PIPE_PRIMITIVE_POLYGON``: The provoking vertex is always the first
vertex. If the caller wishes to change the provoking vertex, they merely
need to rotate the vertices themselves.
-* ``PIPE_PRIMITIVE_QUAD``, ``PIPE_PRIMITIVE_QUAD_STRIP``: This option has no
- effect; the provoking vertex is always the last vertex.
+* ``PIPE_PRIMITIVE_QUAD``, ``PIPE_PRIMITIVE_QUAD_STRIP``: The option only has
+ an effect if ``PIPE_CAP_QUADS_FOLLOW_PROVOKING_VERTEX_CONVENTION`` is true.
+ If it is not, the provoking vertex is always the last vertex.
* ``PIPE_PRIMITIVE_TRIANGLE_FAN``: When set, the provoking vertex is the
second vertex, not the first. This permits each segment of the fan to have
a different color.
