Fix T85426: Speed effect stretch to input not working

`seq_effect_speed_get_strip_content_length()` checked only for number
of inputs of target strip, even if it's not an effect.

Only effects are treated in different way, so check for type as well.

Mask: Use control point position when handle is selected

This is something what comes after an experiment, which makes behavior
more desirable. Basically, for Lock-to-Selection functionality always
use control point position if any of control point itself or handles
are selected.

Initial patch from Sebastian, modification from Sergey.

Fix strict uninitialized warning for C++

Allows to compile Blender without uninitialized warning in Bullet code.

Code quality: Refactor asset operators using C++

* Attempt to improve readability by using focused, coherent helper classes.
* Replace ListBase with blender::Vector, which is more efficient and has a
better API.
* Split user reporting from error checking.
* Use namespace (as we usually do for C++ code).
* Remove unused headers

Cleanup: Remove dead code for keymap Outliner display mode

This wasn't used for a long time and there are no plans to bring this back.

Cleanup: Use enum for Outliner tree-store element types

We generally prefer using enums over precompiler defines. This adds an actual
type for the values, which the compiler can use to throw warnings, give better
messages, etc.

Cleanup: Remove unused tree element types

These weren't used since ages. Comment out the DNA define (value shouldn't be
reused to avoid compatibility breakage) and remove icon code for the types.

Cleanup: Alphabetize function order

Forgot to free a bvhtree with previous commit.

Fix T84493 et al: New Boolean on Suzanne.

While Boolean is not guaranteed to work if the operands are not
volume-enclosing (technically: PWN - piecewise constant winding number),
it needs to do something in those cases. This change makes
more cases meet user expectations in T84493, T64544, T83403,
T82642 (though very slow on that one).
The original new boolean code used "generalized winding number"
for this fallback; replaced this with code that uses raycasting.
Raycasting would have been faster, but for unfortunately also
switchd to per-triangle tests rather than per-patch tests since
it is possible (e.g., with Suzanne) to have patches that are
both inside and outside the other shape. That can make it much
slower in some cases, sadly.

GPencil: Fix wrong python API for Point weights

The old property never worked as expected because it was impossible expose the data as props.

Now, there are two methods to handle this: weight_get and weight_set

Example use:
```import bpy
ob = bpy.context.active_object
gpd = ob.data
gps = gpd.layers[0].frames[0].strokes[0]
i = 0
print("Weightsn================================")
for pt in gps.points:
gps.points.weight_set(vertex_group_index=0, point_index=i, weight=0.5)
i +=1

i = 0
for pt in gps.points:
weight = gps.points.weight_get(vertex_group_index=0, point_index=i)
print(weight)
i +=1
```

Code quality: Port recently added asset files to C++

It seems generally preferred to have new files be created with C++.
The only reason I didn't do that when I initially created the files is that I
was unsure about some C-API aspect.

Also includes some minor C++ related cleanup (nullptr instead of NULL, remove
redundant `struct` keyword).

Code quality: Port recently added utility file to C++

Also use nullptr instead of NULL.

Fix T85378: Shrink/Fatten display number units

Currently the displayed distance when using the shrink/fatten transform
operator does not respect the scene units (they would always be in
blender units).

This changes makes sure the number is displayed in the correct unit.
