This PR adds support for specialization constants for the OpenGL
backend. The minimum OpenGL version we are targetting doesn't
have native support for specialization constants. We simulate this
by keeping track of shader programs for each set of specialization
constants that are being used.
Specialization constants can be used to reduce shader complexity
and improve performance as less registry and/or spilling is done.
This requires the ability to recompile GLShaders. In order to do this
we need to keep track of the sources that are used when the shader
was compiled. For static sources we only store references
(`GLSource::source_ref`), for dynamically generated sources we keep
a copy of the source (`GLSource::source`).
When recompiling the shader GLSL source-code is generated for the
constants stored in `Shader::constants`. When compiling the previous
GLSource that contains specialization constants is then replaced
by the new version.

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

Translation of the UI is currently split into 3 preferences:
interface, tooltips, and new data. The distinction between interface
and tooltips is currently unclear as tooltips also include a lot of
messages not displayed in the actual tooltips on mouse hover.
These include reports to the Info Editor, information in editor
headers and footers, and statuses in panels.
In order to limit the use of `TIP_()` to actual tooltips, this commit
introduces a new preference for this extra information: "Reports".
New translation macros are introduced: `RPT_()` and `CTX_RPT_()`, as
well as their equivalent for the Python API, `pgettext_rpt_()`, to be
imported as `rpt_()`.

This patch implements the Vector Blur node for the Realtime Compositor.
The implementation is a direct and mostly identical port of the EEVEE
motion blur implementation with the necessary adjustments to make it
work with the compositor.
The exposed parameters in the node does not match those exposed in
EEVEE, so only the parameters shared between both are currently
implemented. In the future, we should make a decision to either unify
both, or just consider them independent implementations, with the
possibility of sharing the full or part of the code.
Further, it would also make sense to port the implementation to the CPU
compositor, since the new implementation is higher in quality while also
being faster.
The default value of the node shutter setting was changed to 0.25 to
approximately match the default settings of EEVEE and Cycles, since in
their default settings, they evaluate the previous and next frames at
plus and minus 0.25.

The ruler code would add new (GP) ID and link it to current scene outside
of any depsgraph tagging and/or undo step writing.
Now always add this 'util' GP data earlier, in a context where there is a clear
undo step written. Also fixes the missing tagging and relations updates.

This adds support for rendering the hardness curve attribute.
The attribute cannot be written from within GPv3, but is added when
converting from the legacy Grease Pencil type.
The struct `SpaceText_Runtime` already separates runtime data from
`SpaceText`, however it is still allocated inside `SpaceText`, read and
write file operations still copy this data, but is override on read.
This changes separate allocation of `SpaceText_Runtime` from
`SpaceText`.
Ref !115418
After undo, a depsgraph update could free run-time modifier data.
In the case of the subsurf modifier a reference to this is held
in the meshes run-time data which also needs to be cleared.
When the "before" state of the face set brush gets stored in an undo step
and there is no face set attribute yet, 0 was stored instead of 1. 0 currently
has special meaning and isn't the default white color.
Area for clicking on keys was wider than strip which caused problems.
Instead of finding best strip candidate and then a key, make clickable
area wider, but inside of the strip itself.
These UIs don't display previews, now need to load them.
Currently the UI code doesn't actually know which previews will be
visible, so it loads them all. This adds quite some memory overhead.
Likely fixes#115372.

This fixes an issue where a CacheFile was always created for the USD
file, causing USD_create_handle() to be called unnecessarily even if the
USD does not have animating meshes or transforms.
This bug would sometimes result in the stage remaining open in a
CacheArchiveHandle after import (because the CacheFile is never
freed), preventing the USD from being reloaded from disk.
The cache file is now accessible to readers through an
ImportSettings::get_cache_file function wrapper which creates a
CacheFile as needed, the first time the function is called.
The allocated CacheFile pointer is now stored in a new
ImportJobData::cache_file member.

This adds a Python API for layout panels that have been introduced in #113584.
Two new methods on `UILayout` are added:
* `.panel(idname, text="...", default_closed=False) -> Optional[UILayout]`
* `.panel_prop(owner, prop_name, text="...") -> Optional[UILayout]`
Both create a panel and return `None` if the panel is collapsed. The difference lies
in how the open-close-state is stored. The first method internally manages the
open-close-state based on the provided identifier. The second one allows for
providing a boolean property that stores whether the panel is open. This is useful
when creating a dynamic of panels and when it is difficult to create a unique idname.
For the `.panel(...)` method, a new internal map on `Panel` is created which keeps
track of all the panel states based on the idname. Currently, there is no mechanism
for freeing any elements once they have been added to the map. This is unlikely to
cause a problem anytime soon, but we might need some kind of garbage collection
in the future.

import bpy
from bpy.props import BoolProperty

bl_region_type = 'WINDOW'
bl_context = "scene"

layout = self.layout

layout.label(text="Before")
if panel := layout.panel("my_panel_id", text="Hello World", default_closed=False):
panel.label(text="Success")
if panel := layout.panel_prop(scene, "show_demo_panel", text="My Panel"):
panel.prop(scene, "frame_start")
panel.prop(scene, "frame_end")
layout.label(text="After")
bpy.utils.register_class(LayoutDemoPanel)
bpy.types.Scene.show_demo_panel = BoolProperty(default=False)

Caused bu 5af8b839cf.
This solution tags both mesh positions and normals for update when
drawing happens from the modifier stack evaluation result.
This is needed because the sculpt session modifies original mesh
positions, and the modifier stack is not guaranteed to modify them
further (and hence tag normals for update).

The issue is caused by 087612c042 which changed type of
vpd->paintcol from byte to float. Some of the code was
expecting it to be byte, and did C-style cast to a pointer
of uchar.
This is a minimalistic fix, which makes it so the
paint_and_tex_color_alpha() operates on proper types and
avoids reading from the result color before overriding the
value.

The bone collection unit tests in Python were failing, but this failure
was not propagated to `ctest` and thus went unnoticed.
Both issues are now fixed.
There is currently a bug with autopep8 and Python 3.12, resulting in
the contents of f-strings getting modified when they shouldn't.
As a workaround, "make format" now uses the Python binary bundled with
the precompiled libraries on Linux by default. This matches existing
behavior on macOS and Windows.
