Fix T80885: Texture paint camera project crashes after undo/redo

Unmatched ED_image_undo_push_{begin/end},

Thanks to @Baardaap for the initial fix.

UI: Refactor panel alignment function

This code had grown overly complicated and hard to understand.
The improvements in this commit:
- Avoid allocating a duplicate of every active panel.
- Instead of complicated logic to calculate each panel's offset,
just keep track of the current offset while iterating through.
- More readable code structure, better comments.

Note that calcuting the X offset here is a relic from pre-2.5 when
panels could be aligned horizontally. I kept this in, but it would
be reasonable to remove it in the future.

Cleanup: Rename variables in panel alignment code

This makes these variable names more consistent with current standards,
mostly by not over-abbreviating already short words. The following commit
will refactor this function.

Cleanup: change enum usage so types are explicitly listed

Structure switch statements so new missing items cause warnings.

Cleanup: use 'UI_icon_*' prefix for icons API

- UI_collection_color_icon_get -> UI_icon_color_from_collection
- UI_idcode_icon_get -> UI_icon_from_idcode
- UI_library_icon_get -> UI_icon_from_library
- UI_mode_icon_get -> UI_icon_from_object_mode
- UI_rnaptr_icon_get -> UI_icon_from_rnaptr
- UI_alert_image -> UI_icon_alert_imbuf_get
- UI_preview_render_size -> UI_icon_preview_to_render_size
- UI_id_icon_render -> UI_icon_render_id

Fix T80771: Avoid changing the visibility of loose geometry when entering Sculpt Mode

When entering scultp mode the visibility from the Face Sets is copied to
the base mesh. This steps was considering that if a vertex belongs to a
face with a visibible Face Set ID, it should be visible. As loose
geometry may not have any faces, those vertex were set to hidden.

Now this function check if a vertex visibility should be modified by the
face sets (by checking the loops), avoiding modifying the visibility of
loose geometry unintentionally.

Fix Brushes with deformation target being affected by sim areas

Brushes that target the cloth simulation but are not the cloth brush
affect the entire mesh, so they don't have simulation areas and falloff.

Pointclouds: support mesh <-> pointcloud in convert operator

Just converts verts to points and vice versa.
Materials and Attribute layers are preserved (so for example if you set
custom radii on the pointcloud, convert to mesh, then convert back to
pointcloud, this will be preserved).

Also not add a Radius layer by default (it is still added and
filled when adding a pointcloud object from the menu), a global Radius
property that will be used if there is no radius attribute can be added
later. A Radius attribute can also be added in the pointcloud data
properties (and filled via python).

This will also add a new utility function that copies materials between
datablocks: BKE_id_materials_copy

Cleanup: remove unneeded check in uiTemplateConstraintHeader

Following rB7a0a60dde8b4, checking for temporary IK constraints in
uiTemplateConstraintHeader is not needed anymore (since the whole panel
will now be skipped earlier for those).

Fix T80131: Rigid Body World Field Weights dont have a proper RNA path
(e.g. cannot be animated)

An RNA path is mandatory for RNA_path_from_ID_to_property, and for
EffectorWeights, this has to be provided using RNA_def_struct_path_func
(since this struct is shared across ParticleSettings, Modifiers and Rigid
Body World). Without this, the animation system cannot work and e.g.
keyframes cannot be inserted.

The case for Rigid Body World in rna_EffectorWeight_path was missing,
now added.

Rigid Body World Field Weights are capable of being animated, tested
with file from T80131 (e.g. gravity, wind).
