i965: Enable ES 3.2 sample shading extensions.

This enables:
- GL_OES_sample_shading
- GL_OES_sample_variables
- GL_OES_shader_multisample_interpolation

On Gen8, we pass all the CTS tests, and all but 4 of the dEQP-GLES31
tests (dealing with 1x/2x MSAA at half rate sampling).  We believe
those 4 dEQP-GLES31 tests are incorrect.
