intel: Change supported texture formats for separate stencil

Browse source 
When hardware supports separate stencil, enable support for separate
depth/stencil texture formats in the table
intel_context.ctx.TextureFormatsSupported. If the hardware must use
separate stencil, then disable support for combined depth/stencil formats.
