Remove the box select tool from the timeline to simplify selection
logic, avoid confusion for users, and make maintaining the code
easier in the future. It also brings the selection system closer
to other industry-standard NLEs.
It also fixes an issue caused by d2091b4b1.

When using the `create_collection` parameter during import, the newly
created Collection would be assigned a fake user which isn't necessary
and caused the user count to be 2 instead of the more natural 1 here.
Remove the fake user and add test coverage for the scenario in general.

Clang doesn't allow to capture structured bindings in lambdas.
Instead, remove the structured bindings and just use a const
reference to the item iterator.
This adds a function to merge layers in original Grease Pencil geometry.
It also adds an operator to merge layers as well as some tests for the `merge_layers` function.
The operator has 3 modes:
* `Merge Down`: Combine the active layer with the layer just below (if there is one).
* `Merge Group`: Combine all the layers in a group into one single layer and remove
the group. Can be accessed in the right-click menu of groups.
* `Merge All`: Combine all the layers of the object into one single layer.
All of these can be accessed in the `Extras` menu next to the layer tree.

The `pre` handler is called after blender internal code is done populating
the link/append context with data to be processed, and before this data
starts being linked from library files.
The `post` handler is called after blender is done linking, and
potentailly appending and/or instantiating, the requested data and all
of their dependencies.
Both handlers are called with a single argument, the link/append
context.
An new RNA sets of wrappers have been added to expose relevant info from
these internal C++ structures.
NOTE: !113658 is very similar (but tied to asset drag & drop), whereas
this PR is more general (these could probably live hand-in-hand / side-
by-side).
Implements #122357

Some quick py example code:
```python
import bpy
def my_handler_pre(lapp_context):
print("About to {}:\n\t".format("link" if "LINK" in lapp_context.options else "append"),
"\n\t".join("{} '{}', from libs ['{}']".format(item.id_type, item.name,
"', '".join([l.filepath for l in item.source_libraries]))
for item in lapp_context.import_items))
def my_handler_post(lapp_context):
print("{}:\n\t".format("Linked" if "LINK" in lapp_context.options else "Appended"),
"\n\t".join("{} '{}', from lib '{}'".format(item.id.id_type, item.id.name, item.source_library.filepath)
for item in lapp_context.import_items))
bpy.app.handlers.link_append_pre.append(my_handler_pre)
bpy.app.handlers.link_append_post.append(my_handler_post)

Remove the 'Slotted Actions' (`use_animation_baklava`) experimental flag
from the preferences RNA, in non-experimental builds.
The experimental flag is already zeroed out when loading the
preferences. This commit ensures that it stays zeroed out. The rest of
the code assumes that the flag is always `false` in non-experimental
builds.

Remove some `#ifdef WITH_ANIM_BAKLAVA` guards to make a unit test
succeed. The code is handling slots when assigning Actions to IDs.
Non-experimental builds will only deal with legacy Actions, and thus the
slot assignment is a no-op anyway.
The unit test is explicitly creating layered Actions and running tests
on them. Since this also covers some new code introduced for Action
assignments (unified code for both legacy & layered Actions), I'd feel
more comfortable keeping the test enabled.
Note that when loading a blend file with layered Actions in a
non-experimental build will actually load them as legacy Actions.

This copies the legacy mode toggling operators to a new file
and renames the operators to use the `GREASE_PENCIL_OT` prefix
like the rest of the operators. No functional changes expected.

This fixes two memory leaks:
* Drawings were not properly freed because `MEM_delete` was called on the DNA
base type which does not have the destructor.
* `CustomData` of layers was not freed before it was overridden.

This follows the same pattern as attribute panels for Mesh, Curves, and
Point Cloud. Only the layer domain is supported. The _add_ operator now
has to validate the domain setting on invoke, because layer attributes
don't support the default `Point` domain.

The offset from the surface was calculated based on only the normal
which didn't used to be the case.
The fix computes the offset based on the surface point and the direction
of the view.
Also makes sure to not draw overlays when computing the depths using
`V3D_DEPTH_NO_GPENCIL`.
Wrong `points_num` when resizing the `CurvesGeometry`.
Otherwise, any attriute span will have wrong size, this triggers crash
when writing value in these attribute spans.

Implements scrolling support for tree-views, as well as changing the size of the
scroll-able tree-view. This is important to be able to place them in many places
in the UI, where a compact layout is preferred over an every expanding one
(causing following contents to be scrolled out of view). UI-lists would use
scrolling and resizing to ensure this, now tree-views are on par.
Enables scrolling and resizing for:
- Bone collection UI (`UILayout.template_bone_collection_tree()`)
- Grease Pencil layer UI (`UILayout.template_grease_pencil_layer_tree()`)
- Light link collection UI (`UILayout.template_light_linking_collection()`)
- UI to define a node tree interface (`UILayout.template_node_tree_interface()`)
These are all cases where compact UIs make more sense than expanding ones.
Internally this is enabled by calling the `set_default_rows()` method of the
tree-view, although the API might change still. It shouldn't be quite simple to
implement this for grid-views too if necessary, or other potential view types.
Although I'd like to do some smaller code quality improvements still, this
feature is important for some other modules (e.g. grease pencil module for the
layers UI in grease pencil v3), so I decided to prioritize merging this.

Previously, Cycles only supported the Henyey-Greenstein phase function for volume scattering.
While HG is flexible and works for a wide range of effects, sometimes a more physically accurate
phase function may be needed for realism.
Therefore, this adds three new phase functions to the code:
Rayleigh: For particles with a size below the wavelength of light, mostly athmospheric scattering.
Fournier-Forand: For realistic underwater scattering.
Draine: Fairly specific on its own (mostly for interstellar dust), but useful for the next entry.
Mie: Approximates Mie scattering in water droplets using a mix of Draine and HG phase functions.
These phase functions can be combined using Mix nodes as usual.

The File Output node doesn't write invalid and single value layers,
which can cause differences in EXR structures when rendering animations.
To fix this, we write a dummy image that has the same dimensions as the
other layers in the file, filled with the value of the single value
input.
