Add ANGLE support for ESSL3 variant of mix()

This change adds support for ESSL3 variant of built-in function mix()
that takes last argument as a boolean vector. lerp() - HLSL equivalent
of mix() doesn't look to be supporting a variant that takes last
argument as a boolean vector so emulated it for HLSL.

BUG=angleproject:1006
TESTS=dEQP tests
Fixes "no matching overloaded function found " errors in below tests:
dEQP-GLES3.functional.shaders.constant_expressions.builtin_functions.common.mix_*_b*
(Note: These tests still fail because of constant expression issues)
