Fix composition of render-to-texture widgets on big endian
Converting from QImage::Format_ARGB32 to QRhiTexture::RGBA8 requires
texture swizzling also on big endian. But unlike on little endian it
is not a red/blue swap that is needed, but a rather rotation of the
alpha channel from the first component to the last.
Add a new swizzling mode to the backingstorecompose fragment shader,
and rename the uniform to reflect that it no longer covers only
red/blue swapping.
