v3d: Fix stencil sampling from a separate-stencil buffer.
When the sampler view is in sample-stencil mode, we need to return uint
stencil values. To do that, fill in the format table to return R8I, and
have the sampler view point at the separate stencil buffer.
Fixes dEQP-GLES31.functional.stencil_texturing.format.depth32f_stencil8_2d
