Bastien Montagne ab0bc65c24 Refactor CDData masks, to have one mask per mesh elem type. 
We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.

Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!

As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

Reviewers: brecht, campbellbarton, sergey

* Constraints Graph Notes
*
* For constraints, we currently only add a operation node to the Transform
* or Bone components (depending on whichever type of owner we have).
* This represents the entire constraints stack, which is for now just
* executed as a single monolithic block. At least initially, this should
* be sufficient for ensuring that the porting/refactoring process remains
* manageable.
*
* However, when the time comes for developing "node-based" constraints,
* we'll need to split this up into pre/post nodes for "constraint stack
* evaluation" + operation nodes for each constraint (i.e. the contents
* of the loop body used in the current "solve_constraints()" operation).
