intel: Mark MESA_FORMAT_X8_Z24 as always supported.

Browse source 
This prevents developer surprise at seeing a GL_DEPTH_COMPONENT
texture have stencil bits, and avoids the metaops path accidentally
copying stencil bits around in glCopyTexImage(GL_DEPTH_COMPONENT) (and
being broken because swrast's glReadPixels(GL_UNSIGNED_INT_24_8) is
broken).
