VideoCommon: Work around Adreno TEV zero input miscompilation
Some Qualcomm Android drivers from version 700 onward miscompile
specialized TEV pixel shaders when color input A or B is TevColorArg::Zero.
Use konstLookup[8].rgb, which PixelShaderManager initializes to zero,
to keep these inputs dependent on a uniform value.
Use the existing driver bug gate for OpenGL and Vulkan. Other inputs and
unaffected drivers retain their original shader expressions.
