Add ES3 test for mix intrinsic.
We already had MixFloat (ES2) and MixBool (GLSL 4.5+). However, ES3
only supports `mix(genType, genType, genBType)` and doesn't support
the newer versions of mix which take non-float arguments for X and Y.
This test only covers the `mix(genType, genType, genBType)` form
and excludes the newer forms, which wouldn't be covered by ES2 or ES3.
