Modifiers Evaluation: generate loop normals when requested.

This also fixes T62228.

However, datatransfer code is still doing bad things with its source,
still working on proper changes here.

Multires: Fix crash on exit when sculpting with modifiers

The SubdivCCG structure was re-allocated, but the cached one in
the sculpt session was still pointing to an original one.

This is rather a workaround, but is least evil from what i can
currently think. Remember something similar was also required in
2.7 as well.

Definitely need to revision this change.

Sculpt; Fix memory leak on redraw normals update

Fix T62271: Particles with multires crash on sculpt

In fact, any modifier on top of multires would lead to crash.
Was missing pointer update.

Basically, bring the control flow closer to 2.7.

Image: use sample size instead of radius

It wasn't possible to sample a 2x2 region.

Cleanup: redundant select flush

Tool System: use set/add/subtract for all lasso select operators

Fix T62289: crash with texture paint slots and missing node group datablock.

Multires: Fiux memory leak

The work data for materials flags was never freed.

Refactor building the draw string for floats and ints

Fix T62280: driver functions added in load_post broken after recent changes.

Evaluate the dependency graph a bit later still. This kind of worked before
because it was using the drive namespace from the previously loaded .blend
file but that's of course wrong.

I18n: Enable Thai language.

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).
