Remove clipped_cfg from RestorationState

A RestorationState stores a matrix of restoration units per plane. The
restoration unit associated to a superblock may be retrieved from a
superblock offset.

Although this mapping is independant of subsampling, the superblock
offsets were always converted to plane coordinates, which required to
handle subsampling nonetheless. As a consequence, a PlaneConfig instance
associated to RestorationPlane was necessary to find a restoration unit
from a superblock offset.

Instead, store the (log2) number of superblocks per restoration unit, to
be able to retrieve a restoration unit from a superblock with a simple
shift (without any subsampling information).

That way, we can remove the PlaneConfig associated to RestorationPlane,
which will simplify tiling.
