This renames the `BKE_gpencil_*` as well as the `DNA_gpencil_types.h`
files to indicate that it's the legacy grease pencil.

Mandatory change for the Brush Assets project, from quick test does not
seem to break anything (more) in existing 'old' brushes...
Re. #101908.
Pull Request #105016
This adds a new `Curve Falloff` popover to the comb brush tool settings.
The curve control allows changing the brush weight along the curve to
e.g. affect the tip more than the root. This is a relative way to get
something like stiffness for short hair.
This functionality could potentially be added to some other brushes,
but the comb brush is the most important one, so that is added first.
I did add the buttons add the buttons to choose a curve map preset.
However, I did not add the preset dropdown, because that just adds
some unnecessary complexity in the code now and is redundant.

Also minor changes in comments:
- Reference BLENDER_HISTORY_FILE instead of the literal file-name
(simplifies looking up usage).
- Use usernames in tags, as noted in code-style.
Use a consistent style for declaring the names of struct members
in their declarations. Note that this convention was already used in
many places but not everywhere.
Remove spaces around the text (matching commented arguments) with
the advantage that the the spell checking utility skips these terms.
Making it possible to extract & validate these comments automatically.
Also use struct names for `bAnimChannelType` & `bConstraintTypeInfo`
which were using brief descriptions.
`Brush` has two attributes for holding texture information (`MTex`).
One for color textures (`mtex`) and one for mask textures (`mask_mtex`).
Unfortunately sculpt mode due to reasons used `mtex` to store mask textures.
Changes like brush asset/paint mode require modes/tools to read the mask/color texture from
one place.
To start sanatizing this we isolate the attributes in functions.
`BKE_brush_color_texture_get` and `BKE_brush_mask_texture_get`. All object
paint modes should use these functions.
This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
Add new cavity automasking mode based on local mesh
curvature. Cavity masking is a great way to quickly add
detail in crevices and the like. It's meant to be used
with the Paint brush in color attribute mode. It does
work with other brushes but the results can be unpredictable.

The old "dirty mask" operator has been replace with a new
"mask from cavity" operator that shares the same code with
cavity automasking.
Differences from the sculpt-dev implementation:
* It uses the word "cavity." When I first implemented
this I wasn't aware
this feature existed in other software (and other
paint modes in Blender),
and for reasons that escape me today I initially
decided to call it a concave or
concavity mask.
* The cavity factor works a bit differently. It's
no longer non-linear and functions as a simple
scale around 0.5f.
* Supports custom curves.
* Supports blurring.

This value was used to close gaps, but now with the new system is not needed.
Internally, still we need to keep a small leak size, but after doing a lot of test a
value of 3 is perfect, so it's harcoded.
This new option converts the stroke to outline perimeter as soon as is drawn.
If no alternative material is set, the actual material is used.
The algorithm is similar to the new operator in D15664
