Move all mask-related fields from Object and OperationDepsNode
to Object_Runtime and IDDepsNode. Auto-apply DEG_TAG_GEOMETRY
if the mask changes after DEG rebuild. Update DEG API and all
code that uses it.
This fixes "source mesh data is not ready" errors from Data
Transfer modifier when parameters are changed in the UI after
the recent mesh_get_eval_final fix.

This finished old standing TODO which was attempting to
ignore objects of all invisible collections.
The difference here is that we remove invisible bases from
view layers. This guarantees that the evaluated state is
consistent and does not reference original objects.
Among all the lines moved around, the general idea is quite simple.
Actually, there are two ideas implemented there.
First one, is when object itself is tagged for update, we tag its
point cache component for evaluation, which makes it so point cache
is properly reset. We do it implicitly because otherwise we'll need
to go everywhere and add explicit tag in almost all the properties.
Second thing is, we link all collider and force fields to a point
cache component using special type of link. This type of link only
allows flush if change is caused by a user update. This way reset
does not happen when change is caused due to animation, but will
properly happen when user causes indirect change to the objects
which are part of physics simulation.
- Use the original ID pointer for lookup in DEG_get_eval_flags_for_id.
- When the flags change after a DEG rebuild, tag the object for update.
- Instead of mixing int and short in different places, use uint32_t.
This fixes text not updating when a Follow Curve reference is set.
The idea of those flags is to avoid evaluation of operations
which are not needed to bring visible objects to an up to date
state.
Previously, dependency graph attempted to do combine those
into an ID level flag. In practice it proved to be rather
tricky, since there could be dependency cycles on ID level
which will not exist on component level.
The title says it all actually, the idea is to speedup the following case:
- Visible duplicator of a restricted collection (reported as T56512),
One of the questionable change is that none of the view layer bases is
ignored now. This ensures corresponding objects will have copy-on-write
component evaluated, making it possible to access those pointers. The
evaluation of those objects is skipped.

After discussion with Sergey and Dalai, we have decided to remove
this option completely. We're getting to the point where it is almost
impossible to really use 2.8 without COW, and keeping the old option
running ends up diverting dev resources away towards tracking down
and fixing problems with a parallel system that will be going away.
