Edit Mesh: use partial updates editing vertices with number buttons

Use the same partial-update functions used by transform when
editing vertex locations with the number buttons.

This avoids unnecessary calculations for normals and tessellation.

This gives around 1.44x overall speedup on high poly meshes.

UI: support persistent state during number/slider interaction

Support for begin/update/end callbacks allowing state to be cached
and reused while dragging a number button or slider.

This is done using `UI_block_interaction_set` to set callbacks.

- Dragging multiple buttons at once is supported,
passing multiple unique events into the update function.

- Update is only called once even when multiple buttons are edited.

- The update callback can detect the difference between click & drag
actions so situations to support skipping cache creation and
freeing for situations where it's not beneficial.

Undo System: avoid redundant decoding on undo

In most cases the undo system was loading undo steps twice.

This was needed since some undo systems (sculpt, paint, text)
require stepping out of the current undo step.

Use a flag to limit this to the undo systems that need it.

This improves performance for other undo systems.
This gives around 1.96x speedup in edit-mesh for high-poly objects.

Undo: optimize edit-mode undo

- Tag the object data instead of the object when decoding
(this avoids duplicating mesh object-data on each undo-step).
- Calculate face normals as part of multi-threaded tessellation.

This gives ~11% speedup with 1.5x million polygons.

Cleanup: quiet stringop-overflow compiler warning

Cleanup: remove commented code

Replace with brief note in warning.

Cleanup: minor changes to edit-mesh API calls

Rename:

- EDBM_mesh_free -> EDBM_mesh_free_data
BKE_editmesh_free -> BKE_editmesh_free_data

Since this doesn't free the edit-mesh pointer.

- BKE_editmesh_free_derivedmesh -> BKE_editmesh_free_derived_caches

Since this no longer uses derived-mesh, match naming for the related
object function BKE_object_free_derived_caches.

Also remove `do_tessellate` argument from BKE_editmesh_create,
since the caller can explicitly do this if it's needed,
with the advantage that it can be combined with normal calculation
which is faster on high-poly meshes.

Event Simulate: and a --time-actions command line argument

When enabled, print the time taken between running actions.

Cleanup: Use C99 format string for the SIZET_FORMAT macro

All platforms support the proper format string and it's already used in
various other places.

Depsgraph: Implement 'ID_RECALC_GEOMETRY_DEFORM'

During a mesh transformation in edit mode (Move, Rotate...), only part of
the batch cache needs to be updated.

This commit allows only update only the drawn batches seen in
`BKE_object_data_eval_batch_cache_deform_tag` if the new
`ID_RECALC_GEOMETRY_DEFORM` flag is used.

This new flag is used in the transforms operation for edit-mesh and
results in 1.6x overall speedup in heavy subdiv cube.

Fix T88015: Round end caps on Freestyle lines not shaped as documented

This might be an artistic choice, but round end caps are supposed to be
a "half circle centered at the end point of the line" as documented
here: https://docs.blender.org/manual/en/dev/render/freestyle/
parameter_editor/line_style/strokes.html#caps

They are a shashed half circle instead.

This patch makes this pure half circles [and also fixes the case where
thickness of beginning was used for both beginning and end of the
stroke]

Geometry Nodes: Curve Primitive Quadrilateral

This commit adds a curve primitive node for creating squares,
rectangles, trapezoids, kites, and parallelograms. It also includes
a mode where the four points are just vector inputs.

Fix T89040: dependency graph not handling time remapping correctly

In this bug report it resulted in rendering animations stopping too early,
but this affected more areas.

After the previous cleanup commit, it becomes clear that frame and ctime
values were mixed up.

Cleanup: improve naming and comments of scene frame/ctime functions

Confusingly, BKE_scene_frame_get did not match the frame number as expected by
BKE_scene_frame_set. Instead it return the value after time remapping, which
is commonly named "ctime".

* Rename BKE_scene_frame_get to BKE_scene_ctime_get
* Add a new BKE_scene_frame_get that matches BKE_scene_frame_set
* Use int/float depending if fractional frame is expected
