This patch adds a to_curve method to the Object ID. This method is
analogous to the to_mesh method. The method can operate on curve and
text objects. For text objects, the text is converted into a 3D Curve ID
and that curve is returned. For curve objects, if apply_modifiers is
true, the spline deform modifiers will be applied and a Curve ID with
the result will be returned, otherwise a copy of the curve will be
returned.
The goal of this addition is to allow the developer to access the splines
of text objects and to get the result of modifier applications which was
otherwise not possible.

A few related improvements to the three functions:
- Reduce variable scope
- Use for loops instead of while loops
- Use const, bool instead of int
- Generally make logic easier to read
Copy the smooth setting when filling in curve caps.
For drawing this doesn't change behavior as a single normal is used
for all faces.
The difference may be noticed when converting to a mesh or with
modifiers applied.
Bevel caps always had incorrect normals, causing display glitches
in some cases.
It seems this never worked properly (at least 2.79 also had this bug).
Use the projection vector as the normal.
Having up to nine levels of indentation make this function hard to
follow. Instead of indenting the rest of the loop for a simple special
case, just continue.
This commit uses continue in loops and returning early to reduce
indentation in long functions, only where this results in a significant
improvement. Also includes a few LISTBASE_FOREACH macros.
These changes should result in more readable and undestandable code,
especially where while loops were use instead of for loops. They are
not comprehensive, and I skipped wherever the change was not obvious.
Note that possibility to pass the new ID pointer as parameter was kept,
as this is needed for some rather specific cases (like in depsgraph/COW,
when copying into already allocated memory).
Part of T71219.
I think this wasn't allowed before because the section of a curve was
built in multiple parts. But since rBe34d3e32dda7, the whole slice
of a curve is built in one piece, so we can easily support curve
caps for all geometry types, including the new custom profile option.
Note that this also allows "caps" when the fill type is not full.
They could easily be disabled by checking for "Full" fill type
if that was preferred in the future.

This is to improve the case of T71055 where curves share the same batch
cache when they shouldn't.
This however, does not help to fix edit mode display.
The real fix would be to have a similar handling to what the mesh modifiers
do and duplicate the whole Curve data. But this is too much work/change for
the 2.83 release.

There is no user visible difference in standard builds, as there are no
volume modifiers yet. When using WITH_NEW_OBJECT_TYPES some deform only
modifiers are now available for hair and pointcloud objects.

The files are now split up into the following sections:
- `BKE_anim_path.h` and `anim_path.c` for path/curve functions.
- `BKE_anim_visualization.h` and `anim_visualizationanim_path.c` for
animation visualization (mostly motion paths).
- `BKE_duplilist.h` for DupliList function declarations. These were
already implemented in `object_dupli.c`, so they were rather out of
place being declared in `BKE_anim.h` in the first place.
No functional changes.
This is in preparation of new object types. This only changes mesh_eval, we
may do the same for mesh_deform_eval and other areas in the future if there is
a need for it.
This previously caused a bug in T74283, that should be fixed now.

Fix T74283: modifier display lost when moving object in edit mode.
The cause is not immediately obvious so better to revert and look at this
carefully.

- All parts of the code that need tessface should calculate it on demand.
- The check for tessloopnormal mask isn't correct
(since this is loop data, not tessface data).
This is old logic that no longer makes sense in the new depsgraph, and causes
issues when multiple threads try to modify the same bevel object.

Curve function had two arguments:
- for_render, which was originally supposed to be used to control
whether viewport or render visibility for modifiers is to be
used.
- use_render_resolution, which sounds like it is supposed to control
whether viewport or render resolution for curves is to be used.
What is totally confusing is that those arguments were used
interchangeably: sometimes use_render_resolution would control
modifiers visibility.
This commit makes it so there is one single argument for this.

Force Displist to Mesh conversion if there is any modifier.
This is until we find a better way to store the batches per objects.
Also fix draw cache functions that were not returning final mesh edges.
This was caused by curves pointing to each other
creating a cyclic dependency.
While the dependency graph detects this, generating a mesh for render
recursively generates data which cashes in this case.
Add in a check to detect cyclic links.
Note, this bug exists in 2.7x too - but only crashes on render
since 2.7x didn't use 'for_render' when converting data.
