Fix T83673: Custom node trees selectable in nodes modifier

Node tree types from addons were selectable in the modifier's drop-down.
Obviously they didn't do anything, but it shouldn't be possible anyway.
This was just caused by an unimplemented poll function.

Cleanup: Fix capitalization in various places

Approximately 33 changes of capitalization to conform to MLA title style.

Fix T83725 Inconsistent vertex group between exact and fast boolean.

This makes the exact boolean have zero weights for any vertex groups
on any newly created vertices, which is what the fast solver does.

The exact boolean solver was interpolating vertex data when interpolating
loop data in newly created faces. Not sure why I chose that. The Fast
boolean solver doesn't do that, so I stopped doing it too.

Cleanup: removing some uses of equal sign in descriptions

Using 'is/means/equal' words in place of equal sign in descriptions.

Fix weird Swing+Twist decomposition with noncanonical quaternions.

It turns out that after the fix to T83196 (rB814b2787cadd) the matrix
to quaternion conversion can produce noncanonical results in large
areas of the rotation space, when previously this was limited to
way smaller areas. This in turn causes Swing+Twist math to produce
angles beyond 180 degrees, e.g. outputting a -120..240 range.

This fixes both issues, ensuring that conversion outputs a canonical
result, and decomposition canonifies its input.

This was reported in chat by @jpbouza.

UI: Add more property editor operators to IC keymap

As a followup for rB2b3d85d7d6771, this commit adds the remove and
copy operators for grease pencil modifiers, effects, and constraints
where they apply.

Fix T83705: GPencil - Duplicate strokes of destination layer when merge layer

If the destination layer hadn't keyframe, a new keyframe was added and later the merge layer strokes were added, but this could change the animation because the new frame replaced the old drawings of the target layer.

Now, before merge the layer, all keyframes are added in the target layer in order to keep the drawings.

GPencil: Add uniform subdivide BKE to improve interpolation

This patch introduces a new BKE function that performs a uniform subdivide.

The goal of this function is to subdivide the stroke to reach a target number of points while maintaining its shape, color, and weights.
This is done by repeatedly subdividing the longest edge in the stroke. Every subdivision adds a new point at the exact middle point of an edge.

The function is intended to be used in the interpolation operators to give better results when interpolating between different sized strokes.

UI: Allow Outliners to pass selected data-blocks to operators via context

The way the Outliner integrates operations on selected tree elements is known
to be quite problematic amongst developers. The context menu is generated in an
unusual way and doesn't use the normal operator system. Instead, changes are
applied via a recursive callback system. Things are quite ad-hoc, and the
callbacks often implement logic that should not be in the Outliner, but in
entirely different modules. Often these modules already contain the logic, but
as proper operators.

This commit is a step into a hopefully better direction that should allow us to
put actual operators into Outliner context menus. It starts solving the problem
of: How can the Outliner pass selected data to operators. It implements it for
data-blocks only, but other data could do it in the same way.

Idea is to keep doing what operators were initially designed to do: Operate on
context.
Operators can now query a "selected_ids" context member
(`CTX_data_selected_ids()` in C, `bpy.context.selected_ids` in .py). If an
Outliner is active, it will generate a list of selected data-blocks as a
response, via its `SpaceType.context` callback.
Any other editor could do the same.

No user visible changes. This new design isn't actually used yet. It will be
soon for asset operators.

UI: Allow UI to pass focused data-block to operators via context

This is similar to c4a2067130130d, but applies to the general UI and is only
about single data-blocks. Here there was a similar problem: How can buttons
pass the data they represent to operators? We currently resort to ugly ad-hoc
solutions like `UI_context_active_but_get_tab_ID()`. So the operator would need
to know that it is executed on a tab button that represents a data-block.

A single button can now hand operators a data-block to operate on. The operator
can request it via the "id" context member (`CTX_data_pointer_get_type(C, "id",
&RNA_ID)` in C, `bpy.context.id` in .py).
In this commit, it is already set in the following places:
* Generic RNA button code sets it to the pointed to data-block, if the button
represents a data-block RNA pointer property. (I.e for general data-block
search buttons.)
* Data-block selectors (`templateID`) set it to the currently active data-block.
* The material slot UI-List sets it for each slot to the material it represents.
The button context menu code is modified so its operators use the context set
for the layout of its parent button (i.e. `layout.context_pointer_set()`).

No user visible changes. This new design isn't actually used yet. It will be
soon for asset operators.

BLI_getenv has always incorrectly returned ascii rather

on windows as reported in T74510 (but unlikely the root
cause for the issue at hand there)
