rhi: Enable sampler address mode W in the API

Internally this is already supported by all backends. The frontend was just
not exposing addressW, instead defaulting to the (arbitrarily chosen) ClampToEdge.

Add the parameter to newSampler(), but make it optional, defaulting to the more
natural Repeat (because that's what one would get with OpenGL for WRAP_R by default)
