Similar to Difference but produces less contrast.

This patch implements the Track Position node for the realtime
compositor.

Make it more obvious in the name that an operation is not
cheap, and that the function operates on a tracks from
object and does not need a global tracking structure.
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*/`
Push the const usage a bit further for compositor nodes, so that they
are more explicit about not modifying original nodes from the editor.

Use const pointers to ImageSaveOptions and ImageFormatData for API
parameters where appropriate.

* Respect the image file color space setitng for saving in various cases where
it was previously ignored. Previously it would often use the sRGB or Linear
color space even when not selected.
* For the Save As operator, add a Color Space option in the file browser to
choose the color space of the file. Previously this was chosen automatically,
now it's possible to e.g. resave a Linear image as Linear ACES.
* When changing the file format, the colorspace is automatically changed to an
appropriate color space for the file format. This already happened before, but
there was no visibility or control in the operator settings for this.
* Don't change color space when using the Save operator to save over the same
file.
* Fix missing color space conversion for 16 bit PNGs, where it assumed wrongly
assumed ibuf->rect would be used for saving. Add BKE_image_format_is_byte to
more accurately test this.

Inspired by D12936 and D12929, this patch adds general purpose
"Combine Color" and "Separate Color" nodes to Geometry, Compositor,
Shader and Texture nodes.
- Within Geometry Nodes, it replaces the existing "Combine RGB" and
"Separate RGB" nodes.
- Within Compositor Nodes, it replaces the existing
"Combine RGBA/HSVA/YCbCrA/YUVA" and "Separate RGBA/HSVA/YCbCrA/YUVA"
nodes.
- Within Texture Nodes, it replaces the existing "Combine RGBA" and
"Separate RGBA" nodes.
- Within Shader Nodes, it replaces the existing "Combine RGB/HSV" and
"Separate RGB/HSV" nodes.
Python addons have not been updated to the new nodes yet.
**New shader code**
In node_color.h, color.h and gpu_shader_material_color_util.glsl,
missing methods hsl_to_rgb and rgb_to_hsl are added by directly
converting existing C code. They always produce the same result.
**Old code**
As requested by T96219, old nodes still exist but are not displayed in
the add menu. This means Python scripts can still create them as usual.
Otherwise, versioning replaces the old nodes with the new nodes when
opening .blend files.

Make a copy of ImageFormatData that contains the effective color management
settings, and pass that along to the various functions. This will make it
possible to add more complex logic later.
For compositing nodes, passing along view and display settings through
many functions made it harder to add additional settings, so just get those
from the scene now.
Differential Revision: https://developer.blender.org/D14401
Also fixes missing code to read/write/free/copy color management settings
in various places. This can't be set through the UI currently, but still
should be handled consistently.
This is only part of the experimental "Full Frame" mode (disabled
by default). See T88150.
Currently the viewer node uses buffer paddings to display image offset
in the backdrop as a temporal solution implemented for {D12466}.
This solution is inefficient memory and performance-wise. Another
issue is that the paddings are part the image when saved.
This patch instead sets the offset in the Viewer node image
as variables and makes the backdrop take it into account
when drawing the image or any related gizmo.
