The nvc0 nouveau backend already claimed to support format modifiers, but in practice it ignored them when allocating buffers outside of a perfunctory check for the linear modifier in the first element of the format modifier list. This change deduces the supported modifiers, if any, for a given miptree creation request, prioritizes them based on performance and memory waste properties, compares the requested modifiers against the prioritized list of supported modifiers, and overrides the internal layout calculations based on the layout defined by the resulting modifier. Additionally, if modifiers are provided and none are compatible with the miptree creation request, the function now fails. This brings the nouveau behavior in line with other drivers such as i965 and etnaviv.
