Since one user-defined conversion operator is allowed during implicit conversion,
and after this conversion here is a constructor which can accept result
of conversion, there was a backdoor for a vector types to up-cast their
dimensions via cast to pointer type of a component of a vector. Since it was
implicit and non-intentional it led to buffer overflows.

`float4(float3 &)` is currently problematic because of implicit conversions
to and from `float *`. Writing the constructor explicitly fixes the problem.
Also add const to the arguments.

Use static CreateInfos for Overlay-Next shaders using a similar approach to Workbench shader variations.
Remove unused infos and shader sources.
Remove the `gpu_shader_create_info_get_unfinalized_copy` workaround.

Adds antialiasing to curve's handles and thickness to active ones.
Also handles now react to
`Preferences > Interface > Display > Resolution Scale` and
`Preferences > Themes > 3D Viewport > Edge Width` as they do in
legacy curves.

Functional Changes:
- Custom shapes using empties now supports line width.
- Line width is supported on MacOS.
- Fixed Stick bone drawing on MacOS.
Some shaders are duplicated and ported to the new
primitive expansion API.
The legacy code inside `overlay_armature.cc` have been
guarded behind `NO_LEGACY_OVERLAY` which can
be enabled to make sure no legacy code is used unnoticed.
This allows for spotting more easily code that needs to be
ported. Moreover, it is easier to remove this legacy code
when the time comes.

The setting adds the "Custom Shape Wire Width"
option to the "Viewport Display/Custom Shape" section of a pose bone.
As the setting says, this controls how thick the wire is drawn in the viewport.
This is done by adding a geometry shader that makes two triangles out of a line.
The Anti-Aliasing is controlled by the setting
Viewport->Quality->Smooth Wires->Overlay in the user preferences.
## Artifacts
When increasing the line width, the lines start to separate at their vertices.
This comes from extruding each edge along the normal of its direction.
This could be solved by adding round caps in a later PR.

This makes the edit mode drawing for the new curves data more similar
to the old edit mode. Specifically, it draws the evaluated curves now instead
of just a poly curve. Furthermore, it now draws bezier handles as well as
a separate control curve for nurbs curves.

Changes to edit mode mesh overlays, use hue shift instead of color
fading/darkening for selection mode visual differentiation, and some
theme changes to improve the display of mesh edges and faces with good
selection visibility.
- Removed "edge" toggle from edit mode overlays panel.
- No longer halves the edge and face alpha depending on selection mode.
Half the face alpha in wire-frame mode. For better visibility on most
themes.

Rename the `bPoseChannel::flag` `PCHAN_HAS_TARGET` to `PCHAN_HAS_NO_TARGET`
as that is actually the meaning of the flag (in the majority of the code).
Since the flag was so confusingly named, there were some mixups in the
armature overlay drawing code as well, which have been fixed now too.
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
This contains the basis of the new overlay engine.
Only a few overlays are ported for proof of concept of the new design.
This new design unifies the selection drawing with the overlay-next engine.
It now becomes responsible of selection in object mode.
For this we create a dedicated shader module that patches the shaders
for selection.
Note that the gizmo selection still uses the occlusion queries and edit-mode
the current selection engine (select_engine.c).

Additional mat3 constructors added, global variable namespace collisions
for uniform and object color avoided via re-name.
Metal vertex format compatibility added for shaders wherein vertex data
goes through a double-conversion and cannot be implicitly converted during
Metal vertex assembly e.g. bitmasks passed directly as unsigned type in
shader interface for certain shader interfaces.

This should have (mostly) no functional changes.
Support for clipping was added to the shaders but it is not enabled for now
as we wait for the Gpencil engine to support clipping.
Along with the port to createInfo this also:
- Packs constant uniforms in a UBO.
- Share enum declaration and unify names
- Makes codeflow easier to undestand.
- Split grid data to its own struct.
