This patch refactors the texture samples code by mainly splitting the
eGPUSamplerState enum into multiple smaller enums and packing them
inside a GPUSamplerState struct. This was done because many members of
the enum were mutually exclusive, which was worked around during setting
up the samplers in the various backends, and additionally made the API
confusing, like the GPU_texture_wrap_mode function, which had two
mutually exclusive parameters.
The new structure also improved and clarified the backend sampler cache,
reducing the cache size from 514 samplers to just 130 samplers, which
also slightly improved the initialization time. Further, the
GPU_SAMPLER_MAX signal value was naturally incorporated into the
structure using the GPU_SAMPLER_STATE_TYPE_INTERNAL type.
The only expected functional change is in the realtime compositor, which
now supports per-axis repetition control, utilizing new API functions
for that purpose.
This patch is loosely based on an older patch D14366 by Ethan Hall.

The renderdoc integration used to be behind the `--debug-gpu`
command line option. When using `--debug-gpu` outside renderdoc
error messages where displayed that aren't relevant.
This PR adds a specific command line option for the renderdoc
integration. This option will also enable `--debug-gpu`.

This happens even though there is only one user.
The Outliner only implements this `Make Single User` for worlds
(`singleuser_world_fn`) and actions (`singleuser_action_fn`) [it is
questionable if the whole functionality could be removed really, but
this is for another report] and it uses `id_single_user` to do so --
this function does not check if we even have more than one user though,
so data gets duplicated resulting in duplicate worlds or actions even if
they only have one user and shouldnt be touched.
Now let `id_single_user` check usercount and only act if we have more
than one real users.

When creating nodes by dragging a link, it can be convenient to
transfer values from input socket. For reference values, like images,
this may be necessary to avoid unnecessary data-block users. This
patch starts adding such a system. At this moment this only makes sense
for one node (Image Input), but this can be extended to work with other
reference types, different non-reference types and support auto-casting
(if a float is transferred to the Integer Input node).

Previously the only way to control the subtype was to remove the group
input or output and create it again. This commit adds a dropdown to
change an existing socket, for supported socket types.

It was necessary to fix the UI code slightly; the layout's context
wasn't being used in calls to an operator's enum items callback.

The potential optimization in the normal edit modifier when flipping
faces isn't worth the "API impurity" and complexity introduced by
adding poly normal editing as part of the API. This change simplifies
future changes to the ownership of poly normals with a shared cache,
which can prevent recomputing poly normals completely.
Vertex positions and faces aren't changed, so most caches shouldn't
need to be tagged. This removes unnecessary re-computation of bounds,
triangulation, loose edges, etc.

Allows NLA strips to horizontally translated over each other. If a strip is dropped when translating, it'll cause the strip to shuffle into place.

Abstracted large conditional branch in `recalcData_nla` into it's own `nlastrip_fix_overlapping` method for increased readability. No logical changes were made.

No user visible changes expected.
For brush assets, we need a way to store a reference to a brush in .blend files, so that the last active brush can be restored from the file. See #101908. It seems like a generally useful thing to have.
Adds a new DNA struct to store a "weak" asset reference, that is, a reference that can break under a number of circumstances, but should work reliably enough under normal usage. There's no way to reliably reference an asset currently, so this works on a "best effort" basis. It can break when assets are moved inside the asset library, asset libraries are unregistered from the Preferences, or a file is opened on a different machine with different Preferences, for example. It can also break currently if an asset library is renamed.
It contains:
- Information to identify the asset library the asset can be found in.
- A relative "identifier" (currently a relative path) for the asset within the asset library.
There's further code to resolve a weak reference to file paths and Blender library paths.
Part of #101908.

The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
For example
```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```
becomes
```
OIIOOutputDriver::~OIIOOutputDriver() {}
```
Saves quite some vertical space, which is especially handy for
constructors.

The overall goal is to use implicit-sharing in many places in Blender
that currently do unnecessary copies. See #95845 for more details.
This commit only adds the base data structures in blenlib and uses those
in `GeometrySet` and `AnonymousAttributeID`, which used a more ad-hoc
version of implicit sharing already. #105994 lists some more places where
support for implicit sharing can be added (most notably: custom data layers).

It doesn't take much time to know whether all of the curves have more
than a single point, and if that's the case, we know for sure there are
no loose edges in the mesh. This can save time when creating the mesh
draw cache. The time for finding loose geometry goes from 180 ms to
104 ms for a large molecular nodes test file.
For the single-threaded part of the curve to mesh conversion, avoid
writing to two logically separate arrays in the same loop. Instead
run the calculation on two separate threads if the output is large.
Timing for `calculate_result_offsets` when processing 1 million curves:
Before: Average: 10.4 ms, Min: 9.4 ms
After: Average: 9.2 ms, Min: 7.7 ms
Now that mesh primitive nodes calculate their bounds in constant time,
it's worth updating the bounds eagerly when translating a geometry
since doing so should be very cheap and might save a more significant
amount of time if they're needed later.
Also slightly unify the translation functions for the different types.

Vertex paint's filter operators were not properly going through the SculptSession API.
Undo didn't work; sometimes the operators would do nothing or produce corrupted colors.
The `transform_active_color` helper function now handles all of this. It ensures a valid
SculptSession exists and executes an undo push.

Only the text editor supported the primary clipboard & only for modal
selection. Now selecting text in the console & 3D text editing also
sets the primary clipboard under X11 & Wayland.
Notes:
- Pasting from the primary clipboard isn't yet exposed in the key-map
so in practice it's only useful for pasting text outside of Blender.
- Use skip-save option when pasting from the primary selection
so this is never used by the regular paste shortcut.
- This commit adds a primary-clipboard flag to WM_capabilities_flag() so
creating the the copy-buffer is only performed when necessary.
These `ME_POLY_LOOP_PREV` are redundant, since they're similar to
the `poly_corner_prev` inline functions. They were also confusing,
since they took an index into the poly and returned an index into
the entire corner range. Instead structure code to use the function
version, and simplify some loops in the process.
Standardize naming, use spans and references for input parameters,
and improve documentation. Now the functions expect the lookups to
succeed as well, they will fail and assert otherwise.
The functions are also simple enough that it likely makes sense to keep
them all inlined
This allows adding spans, arrays, etc. directly to SculptSession, which
simplifies accessing mesh data, especially in #105938. A few files
aren't moved to C++ yes, so I had to add three C accessor functions.
