multi-texture-format: Generalize shader names

Browse Source 
These shaders can be used for similar formats with other component
sizes since the values are represented as floats. So whether the source
value was stored in 8bit, 10bit or 16bit doesn't matter - the driver
will covert it for us.

Thus use a Weston-inspired, more general naming scheme.
