Snap to geometry is not supported when moving camera in camera view.
This is because the camera would make jumps that would be difficult to
predict and control.
The same happens if Snap Base were supported.
Therefore, disable Edit Snap Base when transforming camera into camera
view.
Discussed in #114646.
This commit transforms the "alt_navigation" option of the transform
operators into a new modal key item. "PASSTHROUGH_NAVIGATE"
In addition to cleaning up a lot of the code, it allows you to
customize the key chosen to navigate while transforming.
This adds the keybindings, menu, and functionally for the edit mode transform operators to grease pencil v3.
The transform operation include:
* translate, rotate, scale, change opacity, change radius

This PR replaces the auto smooth option with a geometry nodes modifier
that sets the sharp edge attribute. This solves a fair number of long-
standing problems related to auto smooth, simplifies the process of
normal computation, and allows Blender to automatically choose between
face, vertex, and face corner normals based on the sharp edge and face
attributes.
Versioning adds a geometry node group to objects with meshes that had
auto-smooth enabled. The modifier can be applied, which also improves
performance.
Auto smooth is now unnecessary to get a combination of sharp and smooth
edges. In general workflows are changed a bit. Separate procedural and
destructive workflows are available. Custom normals can be used
immediately without turning on the removed auto smooth option.
**Procedural**
The node group asset "Smooth by Angle" is the main way to set sharp
normals based on the edge angle. It can be accessed directly in the add
modifier menu. Of course the modifier can be reordered, muted, or
applied like any other, or changed internally like any geometry nodes
modifier.
**Destructive**
Often the sharp edges don't need to be dynamic. This can give better
performance since edge angles don't need to be recalculated. In edit
mode the two operators "Select Sharp Edges" and "Mark Sharp" can be
used. In other modes, the "Shade Smooth by Angle" controls the edge
sharpness directly.
### Breaking API Changes
- `use_auto_smooth` is removed. Face corner normals are now used
automatically if there are mixed smooth vs. not smooth tags. Meshes
now always use custom normals if they exist.
- In Cycles, the lack of the separate auto smooth state makes normals look
triangulated when all faces are shaded smooth.
- `auto_smooth_angle` is removed. Replaced by a modifier (or operator)
controlling the sharp edge attribute. This means the mesh itself
(without an object) doesn't know anything about automatically smoothing
by angle anymore.
- `create_normals_split`, `calc_normals_split`, and `free_normals_split`
are removed, and are replaced by the simpler `Mesh.corner_normals`
collection property. Since it gives access to the normals cache, it
is automatically updated when relevant data changes.
Addons are updated here: https://projects.blender.org/blender/blender-addons/pulls/104609
### Tests
- `geo_node_curves_test_deform_curves_on_surface` has slightly different
results because face corner normals are used instead of interpolated
vertex normals.
- `bf_wavefront_obj_tests` has different export results for one file
which mixed sharp and smooth faces without turning on auto smooth.
- `cycles_mesh_cpu` has one object which is completely flat shaded.
Previously every edge was split before rendering, now it looks triangulated.

No functional changes
The following functions have been moved
`autokeyframe_cfra_can_key`
`autokeyframe_object`
`ED_autokeyframe_object`
`ED_autokeyframe_pchan`
`ED_autokeyframe_property`
they are all in a new file
keyframing_auto.cc
while the declarations are in
ANIM_keyframing.cc
The autokeyframe makros also have been moved

There are a couple of functions that create rna pointers. For example
`RNA_main_pointer_create` and `RNA_pointer_create`. Currently, those
take an output parameter `r_ptr` as last argument. This patch changes
it so that the functions actually return a` PointerRNA` instead of using
the output parameters.
This has a few benefits:
* Output parameters should only be used when there is an actual benefit.
Otherwise, one should default to returning the value.
* It's simpler to use the API in the large majority of cases (note that this
patch reduces the number of lines of code).
* It allows the `PointerRNA` to be const on the call-site, if that is desired.
No performance regression has been measured in production files.
If one of these functions happened to be called in a hot loop where
there is a regression, the solution should be to use an inline function
there which allows the compiler to optimize it even better.

"Auto Keying On" display now respects users MINI_AXIS preferences (default, minimal, none), as well as the navigation (en)disable option. No more text overlapping.

Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.

Regression caused by 03f17c42d0
In that commit it was assumed that the hotkey modifier `S` had no
influence if we were already resizing.
But this is not the case in tracking. The second `S` has influence and
should not be filtered.
The solution is to add a conditional only to Trackers transformation.
This commit also fixed the canceling of this transformation which did
not revert the search area to its original value.
Caused by 5ed14e9269.
That commit accidentally removed the `copy_v2_v2_int(t->mval, mval);`
line which was responsible for initializing the value of `mval`.
In the 3D View, after navigating, the initial cursor position was
updated based on the relative position of the cursor in 3D space.
Now the initial relative position is maintained but moved closer to or
further from the 2d center based on zoom.
