Skip testing of stencil textures where non-readable.

Browse Source 
Readback of stencil is not supported on vanilla ES, so we introduce a toggle to disable it. NVidia GLES drivers support NV_stencil_read and NV_depth_stencil_read extensions, so we use those where available.

It turns out ANGLE supports NV_stencil_read but not NV_depth_stencil_read (for reading from the packed depth/stencil buffers which Dawn uses), so that's the extension we check for.
