Split much of BKE_pbvh.h into BKE_pbvh_api.hh.
BKE_pbvh.h is included by BKE_paint.h, which in
turn is included by large amounts of code including
RNA.
This makes it extremely difficult to change
or clean up the PBVH API, since each modification
of BKE_pbvh.h can take 20-30 minutes to compile,
even on a quad-core system with an SSD. This
commit fixes that by moving most of BKE_pbvh.h
into another file and just having the core,
external-facing interfaces in BKE_pbvh.h.
String search & replace is a higher level function (unlike BLI_string.h)
which handlers lower level replacements for printing and string copying.
Also use BLI_string_* prefix (matching other utilities).
This makes it possible to use BLI_string in Blender's internal utilities
without depending on DynStr, MemArena... etc.
Replace `typedef struct X {} X;` with `struct X {};`
In some cases the first and last name didn't match although this
is rarely useful, even a typo in some cases, e.g. TrachPathPoint.
`CD_HAIRLENGTH` is not really a custom data type, it was just used to
specify the hair particle "length" attribute to pass it to EEVEE and
material preview. Because of the "typemap" array in `CustomData`,
it's better not to have this unnecessary type. Instead, use the same
mechanism used to request the active color attribute.

Resolves failing unit tests where missing texture read support for
1D/3D textures was required. Also resolves a number of missing
format support cases when determining texture component
count and byte size for reading/writing.

* opengl_context -> system_gpu_context. This is the operating system OpenGL,
Metal or Vulkan context provided by GHOST.
* gpu_context -> blender_gpu_context. This is the GPUContext provided by
the Blender GPU module, which wraps the GHOST context and adds some state.
* Various functions create/destroy/enable/disable both contexts, these have
just gpu_context in the name now.

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:

Resolve an issue where a high resolution texutre 16k x 8k
did not update in metal due to integer overflow of size parameter.
This patch contains several changes to address size correctness
across multiple use cases within the Metal backend.

Method didn't modified the ShaderInterface but wasn't usable when trying
to debug a const reference to the ShaderInterface. This PR just adds the
const to the method.

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).

Adds stencil texture view support for Metal, allowing reading of
stencil component during texture sample/read.
Stencil view creation refactored to use additional parameter in
textureview creation function, due to deferred stencil parameter
causing double texture view creation in Metal, when this should
ideally be provided upfront.

Texture clearing is done using framebuffer clear.
To avoid adding the flag everywhere we add it as part
of the texture creation process.
This should have no performance impact.
See: https://projects.blender.org/blender/blender/issues/103343
Changes:
1. Added `BKE_node.hh` file. New file includes old one.
2. Functions moved to new file. Redundant `(void)`, `struct` are removed.
3. All cpp includes replaced from `.h` on `.hh`.
4. Everything in `BKE_node.hh` is on `blender::bke` namespace.
5. All implementation functions moved in namespace.
6. Function names (`BKE_node_*`) changed to `blender::bke::node_*`.
7. `eNodeSizePreset` now is a class, with renamed items.

This patch implements the Convert Color Space node for the realtime
compositor. A custom OCIO GpuShaderCreator was implemented to use the
ShaderCreateInfo in constructing the OCIO GPU processor shader. That
shader is then cached inside the cache manager and is invalidated when
the OCIO configuration changes.

For derived mesh triangulation information, currently the three face
corner indices are stored in the same struct as index of the mesh
polygon the triangle is part of. While those pieces of information are
often used together, they often aren't, and combining them prevents
the indices from being used with generic utilities. It also means that
1/3 more memory has to be written when recalculating the triangulation
after deforming the mesh, and that the entire triangle data has to be
read when only the polygon indices are needed.
This commit splits the polygon index into a separate cache on `Mesh`.
The triangulation data isn't saved to files, so this doesn't affect
.blend files at all.
In a simple test deforming a mesh with geometry nodes, the time used
to recalculate the triangulation reduced from 2.0 ms to 1.6 ms,
increasing overall FPS from 14.6 to 15.

When creating a texture view, Metal may require that the original
GPUTexture state is modified in some way. This may be a result
of deferred creation, or, to cache the texture view against the
source.
As a result, GPUTexture passed into GPU_texture_create_view
cannot be const.
Small fixes have also been made in the Metal texture
implementation to ensure correct function of texture views.

Add texture usage flags for textures which are used as texture views
or require texture views for backing implementation.

- Use off-screen drawing when reading from the front-buffer isn't
supported.
- Add a capabilities flag for reading the front-buffer which is always
disabled on WAYLAND.
- Add GPU_offscreen_read_pixels_region, used for reading a sub-region of
an off-screen buffer - use for color-picking a single pixel.
Currently the Textures used for offscreen rendering don't have
the `GPU_TEXTURE_USAGE_HOST_READ` flag. But some cases it is
needed. This PR adds a parameter when creating an offscreen
buffer.
Other solution could be to add this flag to all textures, but
we chose not to do this as that reduces the amount of fine-tuning
options for Metal/Vulkan backends. GPU can store textures
differently based on its actual usage.
This option isn't available in the python API as we don't expect
add-on developers to fine-tune texture usages to this extent.
For convenience `GPU_TEXTURE_USAGE_ATTACHMENT` is by default
always added.

This function was not exposed outside of internal GPU module.
Renaming `draw::Texture::depth()` to `is_depth` for consistency
and removing the ambiguity.
