It is a know issue that split normals aren't supported when using high quality normals in the viewport. Some AMD platforms were pushed to use high quality normals to work around a driver bug where 1010102 texture formats `GL_INT_2_10_10_10_REV` wasn't uploaded to the GPU. This change will remove commonly used polaris platforms from the work-around. This has been tested with a RX480 against the latest AMD whql drivers (22.5.1). Users need to ensure that they use the latest drivers that are available on their platform. Although this change doesn't fix the underlying issue to support edit normals when high quality normals are enabled. It will not force that common platforms cannot use a feature as their platform is forced into using a work-around.
