BKE mesh remap: add utils to add needed cddata mask for source mesh.
In some cases (currently, only when using avanced mapping of loops),
code needs access to some cddata of the source mesh (CD_NORMAL...).
We need a way to inform calling code about that (actual issue requiring
this change is fixed in next commit).
