mesa: Implement glGet*(GL_PRIMITIVE_RESTART_FOR_PATCHES_SUPPORTED).
Technically, this was introduced with GL 4.4. However, I believe it
was intended to be retroactive. As far as I know, AMD has never
supported primitive restart with patches, while NVidia and Intel do.
This necessitated the need for a query which would allow applications
to figure out whether this was usable or not.
I decided to expose it everywhere ARB_tessellation_shader is exposed.
(It's also in both OES and EXT_tessellation_shader.)
Enable this for i965 and Gallium drivers which expose the capability.
v2: Fix a bug in the state_tracker code (caught by Ilia Mirkin).
