Multires: Remove legacy compatibility code

It was rather a huge chunk of code, which started to become
more harder to maintain with the transition to OpenSubdiv based
implementation. Because of this transition, the compatibility was
also rather on a poor side.

Remove compatibility support for pre-2.50.9 multires.
