Sculpt: Show paint brush cursor in all tools

This patch enables the paint brush cursor with all tools in sculpt mode,
even with the ones that are not brushes. The motivations for this change
are:
- The filters are using the position of the active vertex for certain
features without any visualization of what the active vertex is.

- You can call operators like mask expand (which depends on the brush
cursor position and active vertex) with a non brush tool enabled.

- Having the cursor in the rest of the tools allows to have a scene
scale representation of the radius and a direct control of radius and
strength (using the current brush shortcuts), which will allow to make
features more intuitive without relying on modifying values in the
topbar. For example, the brush radius can be used to control the depth
of the cut in the trimming tools or the size of the sphere in the
sphere mesh filter

Fix mask expand creating wrong masks when the cursor is not over the mesh

This forces the mask expand modal operator to use the maximum
iteration when the cursor is not over the mesh, masking the entire
connected component.

This fixes the issue for both expanding masks and face sets.

Sculpt: Experimental Pen Tilt Support

This adds support for pen tilt in sculpt mode. For now, pen tilt is used
by tweaking the tilt strength property, which controls how much the pen
angle affects the sculpt normal. This is available in Draw, Draw Sharp,
Flatten, Fill, Scrape and Clay Strips brushes, but it can be enabled in
more tools later.

The purpose of this patch is to have a usable implementation of pen tilt
in a painting mode, so users can test and see in which hardware and
platforms this feature is supported and how well it works. If it works
ok, more tools and features that rely on pen tilt can be implemented,
like brushes that blend between two deformations depending on the angle.

Fix T80625: Trimming tools not working with transformed objects

The code to handle object transforms was wrong. Now the trimming mesh
and depts is calculated in world space, using the real view origin and
normal and then stored in object space in the mesh and in the original
coordinates array. As now both meshes for the boolean operation are in
the same object space, the space conversion code can also be removed
from the boolean function.

Improve Voxel Remesher volume projection artifacts on sharp edges

The voxel remesher was using the voxel size to limit the shrink-wrap
projection distance. Now that distance is increased to help preserving
more detail on hard surface edges.

Fix T81697: Property search crash with python handlers

Previously I used `CTX_copy` to create a mutable copy of the context in
order to set its area and region fields to temporary variables. This was
a tradeoff to avoid casting away `const` for `bContext`.

However, `bpy.context` is set to this new temporary value, which is fine
for a single `wm_draw_update` pass, but in the next main loop,
`bpy.context` is still set to this value, which was freed at the
end of `property_search_all_tabs`. It would be possible to reset the
`bpy.context` variable ath the end of the function, but this patch
contains an alternate solution: just don't copy the context. It looks
like this was the only use of `CTX_copy` anyway, maybe for good reason.

UI: Add reset to default value to keymap

With all the work on DNA defaults for 2.91, it's nice to expose this
convenient operator. This was already hardcoded in the UI code to the
backspace key, adding it to the keymap instead will make the shortcut
automatically show in the button right click menu.

Cleanup: Use DNA defaults for grease pencil modifiers

This will make "Reset to Default Value" work properly for grease

CMake/macOS: set package_ROOT for PNG, JPEG, TIFF

https://devtalk.blender.org/t/libpng-version-mismatch/15799/

In this case, CMake finds libraries in `LIBDIR`, but picks headers from
`/Library/Frameworks/` (Mono framework).

CMP0074 is already enabled, so use it.

Cleanup: Animation, simplify channel selection code

Split up `ANIM_deselect_anim_channels()` into
`ANIM_anim_channels_select_set()` and
`ANIM_anim_channels_select_toggle()`.

`ANIM_anim_channels_select_set()` is equivalent to the old
`ANIM_deselect_anim_channels(..., false, ACHANNEL_SETFLAG_xxx)`.

`ANIM_anim_channels_select_toggle()` is equivalent to the old
`ANIM_deselect_anim_channels(..., true, ACHANNEL_SETFLAG_ADD)`.

`ANIM_deselect_anim_channels(..., true, ACHANNEL_SETFLAG_CLEAR)` was
also called once. The `true` parameter suggested the "toggle" behaviour
was intended, but the `ACHANNEL_SETFLAG_CLEAR` argument prevented any
toggling. This is now replaced with `ANIM_anim_channels_select_set(ac,
ACHANNEL_SETFLAG_CLEAR)` to make this explicit.

No functional changes, just a cleanup in order to better understand how
the selection works.

Cleanup: Animation, rename function to match operator

Rename `animchannels_deselectall_exec` ? `animchannels_selectall_exec` so
that it matches the operator `ANIM_OT_channels_select_all`.

No functional changes.

Fix part of T74918: 3D Viewport: Jump, when mouse crosses a window corner.

We need a separate time stamp for each axis, and we have to add a few
milliseconds of padding to those, to ensure wrapping on both axes get
properly performed when it happens almost simultaneously, and avoid
extra wrapping caused by very close events sometimes.

This only addresses the Linux (X11 backend) case.

Cleanup: remove duplicate context variable (__py_context)

The context was stored both in __py_context & bpy_context_module.

This avoids duplicate functions to update them too.
