gallium: add a pipe cap for determining driver support for prim type in restarts

Browse Source 
this is another prim type bitmask which will trigger automatic draw rewriting
to a direct draw any time a prim-restart draw occurs with a prim type that is
not supported by the driver for prim restart, even if that prim type is supported
for normal drawing

the default is set to all prim types to preserve existing functionality, and PrimitiveRestartForPatches
is now explicitly set to false because no driver supports it

* ``PIPE_CAP_SAMPLER_REDUCTION_MINMAX_ARB``: Driver supports ARB min/max sampler reduction with format queries.
* ``PIPE_CAP_EMULATE_NONFIXED_PRIMITIVE_RESTART``: Driver requests all draws using a non-fixed restart index to be rewritten to use a fixed restart index.
* ``PIPE_CAP_SUPPORTED_PRIM_MODES``: A bitmask of the ``pipe_prim_type`` enum values that the driver can natively support.
* ``PIPE_CAP_SUPPORTED_PRIM_MODES_WITH_RESTART``: A bitmask of the ``pipe_prim_type`` enum values that the driver can natively support for primitive restart. Only useful if ``PIPE_CAP_PRIMITIVE_RESTART`` is also exported. ``PIPE_PRIM_PATCHES`` must be supported to prevent incorrect lowering of primitive restart.
