[m91] Do not use single component texture with vulkan webview

Currently there is no cross-thread interop (gl-vulkan) shared
image implementation that supports single component textures (r8).
So disable single texture in this case.

Note this has the side effect of restoring the workaround for
PowerVR devices as well, which was lost when shared image was
enabled. The (non-functioning) code was removed in this CL:

(cherry picked from commit 871e70e)
