Fix T80623: Correct Face Attributes affecting modes not listed

Some transform modes (such as Mirror) are not listed to have UV corrected
during the transformation.

It messed up the UV of all of these.

Fix T78225: Vertex Colors not showing in edit mode

This should be using the mesh_cd_ldata_get_from_mesh function in
order to get ldata from BMesh in edit mode.

Fix T80372: Mantaflow Noise Not working with Smoke/Smoke and Fire

Modular caches for noise, particles and meshes require that additional data is baked (i.e. is resumable option). With this commit users will be explicitly asked to enable this option before being able to bake noise, particles or meshes.

Fix T79626: 2.91 Mantaflow crash when adaptive domain + noise are enabled

Crash was caused by an incorect domain size of the noise solver and an index out of bounds.

Fix T80516: Hook modifier crashes without vertex group data

Fix T80464: Crash deleting bone constraints when the armature layer is
not active

Caused by {rB608d9b5aa1f1}

Prior to rB608d9b5aa1f1, the constraint was gotten using **context**
[CTX_data_pointer_get_type(C, "constraint", &RNA_Constraint) -- which is
valid for bones on hidden layers].
After rB608d9b5aa1f1, the constraint is found (or isnt) using
`edit_constraint_property_get` [this is **not** valid for bones on
hidden layers because internally `BKE_pose_channel_active` checks if the
bone is on an active layer].

Some observations:
- Every operator using `edit_constraint_property_get` doesnt work for
bones on inactive layers [delete, moveup, movedown, move to index (drag
n drop nowadays)]
-- moveup, movedown, move to index check if they could find a constraint
beforehand though (dont crash)
-- delete crashes (doesnt check if a constraint could actually be found)
- Every operator using `edit_constraint_property_get` for constraint
data doesnt work for bones on inactive layers [stretchto_reset,
limitdistance_reset, childof_set_inverse, ...]
-- these all check if they could find a constraint beforehand though
(dont crash)

This is because the poll function is using **context** to get the
constraint, the operators themselves use
**edit_constraint_property_get** which leads to inconsistent/unexpected
results.

Possible solutions were:
- [1] let the delete operator just work with the context constraint
again (like prior to rB608d9b5aa1f1) -- allows for deleting constraints
on bones in inactive layers
- [2] check if we could get a constraint -- prevents the crash, but does
**not** allow for deleting constraints on bones in inactive layers
- [3] make the poll `edit_constraint_poll_generic` be as strict as the
operators -- dont use **context** to get the constraint, but something
like **edit_constraint_property_get**
- [4] make the operators be more graceful and let them act on bones on
hidden layers -- let **edit_constraint_property_get** actually use the
same **context**

This patch implements [4], so poll an doperators are now in sync.
- prevents reported crash
- also enables operators for bone constraints on hidden layers
- also enables drag and drop reordering of constraints on hidden layers

This might be a candidate for 2.90.1? (if it is, take care to include
prior "Refactor getting constraints" refactoring commit)

Note: Adding constraints also doesnt work for bones on inactive layers
[that was the case in 2.79 as well -- it is also using
`BKE_pose_channel_active`]

Fix for failing constraints test

Caused by own rB6dc7266cf1f4.

When overriding context for constraint operators (such as in constraint
tests), it could happen that context "active_pose_bone" is set, but
"pose_bone" isnt. Now check for both in ED_object_pose_constraint_list.

Refactor getting constraints

This is the refactoring part of D8805 (should be no functional changes).

- exposes pose-related part of former 'get_constraints()' from
interface_templates.c to new ED_object_pose_constraint_list
- rename ED_object_constraint_list_from_context -->
ED_object_constraint_active_list

Also clarify comments on both of these.

Fix T80604: BLI_polyfill_calc exceeds stack size allocating points

On systems with 512kb stack this happened at around 13k points.

This happened at times with grease-pencil, although callers that
frequently use complex polygons should be using BLI_polyfill_calc_arena.

Fix T80238: Crash adding properties to material node-trees

The localized node-tree was freeing the materials ID properties twice.

This matches how animation data behaves, setting to NULL after freeing.

PY API doc: fix doc for new override option of properties.

Reported by Demeter Dzadik (@Mets) on blender.chat, thanks.

Candidate to be backported to a potential 2.90.1.

Fix T80561: Crash when multi-mesh editing UVs with proportional editing

Because of a `goto` we would free a variable before it was declared.
Declare it before the `goto` and `NULL`-check the value before freeing.

Fix T79718: Eevee OpenVDB render error when frames miss part of the grids

Improved fix that handles the distinct cases of missing grids and zero

Fix T80332: principle volume shader not working for world in Eevee

The handling of missing volume grids for the principled volume shader was
incomplete, different inputs need different default values.

Fix T80224: Crash after duplicating and hiding vertices while using X Axis Mirror

The mirror map can reference a hidden vertex that is currently ignored
in the transformation.

Thus the mirror element array is not filled.
