GPU: Enable HQ normal work around for AMD Polaris 

THe high quality normals work around is enabled for Polaris cards using
the official drivers. Since driver version 2.11.2 they fail to render
using low quality normals.

The detection of polaris cards is done by matching the opengl renderer.
The renderer strings have been extracted from various reports linked to
{T82856} but isn't complete as some reports are missing the exact
renderer as users don't always report via the help menu.
