gallium: Add PIPE_CAP_GLSL_TESS_LEVELS_AS_INPUTS

In the Intel backend, it makes the most sense to treat gl_TessLevelInner
and gl_TessLevelOuter as ordinary shader inputs.  For Radeon, it makes
more sense to treat them as system values which get special handling.

We already have a compiler option for this, but the Iris driver will
need a capability bit so we can set it appropriately.
