drm/nouveau/kms/nv50-: Add .blend_modes to nv50_wndw_func

At the moment, we currently (incorrectly) only expose a blend property on
the plane if we have a nv50_wndw_func->blend_set function for the given
wndw type. But we need to expose a blend property for all types of planes
that can display color formats with an alpha channel.

Prepare for doing this by introducing a way of looking up the supported
blend modes for a type of wndw by introducing .blend_modes, which describes
all possible blending modes nouveau currently supports for a type of wndw.
