Allow SVG files to have previews in the File Browser. Adds
nanosvgrast.h to extern\nanosvg\, which is an SVG rasterizer that is
an optional part of the nanosvg source.

Doing so avoids having duplicated logic for working with pixel
data which is being passed throughout the render pipeline.
Notable changes:
- ImBug can now store GPU texture.
This is not very finished part of the API, which will be
worked further to support tiling for very-high-res images.
- Implicit sharing is removed from the image buffer, as it is
no longer needed.
There should be no functional changes on user level with this
change.

There's quite a few libraries that depend on dna_type_offsets.h
but had gotten to it by just adding the folder that contains it to
their includes INC section without declaring a dependency to
bf_dna in the LIB section.
which occasionally lead to the lib building before bf_dna and the
header being missing, while this generally gets fixed in CMake by
adding bf_dna to the LIB section of the lib, however until last
week all libraries in the LIB section were linked as INTERFACE so
adding it in there did not resolve the build issue.
To make things still build, we sprinkled add_dependencies wherever
we needed it to force a build order.
This diff :
Declares public include folders for the bf_dna target so there's
no more fudging the INC section required to get to them.
Removes all dna related paths from the INC section for all
libraries.
Adds an alias target bf:dna to signify it has been updated to
modern cmake
Declares a dependency on bf::dna for all libraries that require it
Removes (almost) all calls to add_dependencies for bf_dna
Future work:
Because of the manual dependency management that was done, there is
now some "clutter" with libs depending on bf_dna that realistically
don't. Example bf_intern_opencolorio itself has no dependency on
bf_dna at all, doesn't need it, doesn't use it. However the
dna include folder had been added to it in the past since bf_blenlib
uses dna headers in some of its public headers and
bf_intern_opencolorio does use those blenlib headers.
Given bf_blenlib now correctly declares the dependency on bf_dna
as public bf_intern_opencolorio will get the dna header directory
automatically from CMake, hence some cleanup could be done for
bf_intern_opencolorio
Because 99% of the changes in this diff have been automated, this diff
does not seek to address these issues as there is no easy way to
determine why a certain dependency is in place. A developer will have
to make a pass a this at some later point in time. As I'd rather not
mix automated and manual labour.
There are a few libraries that could not be automatically processed
(ie bf_blendthumb) that also will need this manual look-over.

The file-name would be included twice, because an_stringdec worked
differently to BLI_path_sequence_encode.
Use BLI_path_sequence_{encode/decode} to resolve the issue.
While image-sequence `anim` doesn't seem to be relied on, it's
possible to use this code-path by referencing an image from a movie
sequence strip.
It was only used by OpenEXR and Iris images, and saving the Z Buffer
in those formats was disabled by default. This option comes from the
times prior to the addition of the Multilayer EXR.
It also worth noting that it was not possible to save Iris with Depth
pass from Blender as internally it is called IRIZ format and it was
not exposed. But even after exposing this format option something still
was missing as saving and loading ITIZ did not show up the Depth pass.
The reason of removal is to make it a more clear match of the ImBuf
with a render pass, and use it instead of a custom type in the render
result and render pass API. This will simplify the API and also avoid
stealing buffers and making shallow copies when showing the render
result.
For the cases when Depth is needed a Multilayer EXR is to be used,
as most likely more than just the Depth will be needed.
On a user level this change:
- Removes the "Z Buffer" option from the interface.
- It preserves existing sockets in compositor nodes, but it will
output black image. Also changing the image data-block will
remove the socket unless a Multilayer EXR with Depth pass image
is selected.
- Removes "Depth" socket of the Viewer and Composite nodes.

Prior to using OIIO for image loading, DDS files were hard-coded to
always treat files with BC5/ATI2 compression as normal maps[1].
This basically means that the B channel would be reconstructed from the
R,G channels in a particular way. There is a non-standard header flag
(coming from tools like NVTT and various others) that can also be used
to indicate if such processing should take place, and OIIO understands
that flag and acts appropriately. However, not all files have that flag
set.
This patch reverts to the hard-coded behavior to match prior versions.
If the user has explicitly set the OIIO environment variable to say
otherwise, we will respect that setting instead.

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.
Before this change the ImBuf struct had dedicated fields for the
buffer data. Now the color space is stored inside of the struct
which wraps around the buffer information.
This only changes the field placement, without changing the way
it is handled. In the future one might imagine that operations
like stealing buffer data should null-ify the buffer colorspace
pointer. Such changes would need to have more accurate thinking
before implementation.
Should be no functional changes.

Since avuitl 57.30.100 the pkt_duration is deprecated, and
the duration is to be used instead.
The units seems to match, and also from the avcodec decoder.c
the `frame->pkt_duration = frame->duration;` so does not seem
we need to do any conversion.
The change in FFmpeg is from 2022, which is a bit recent, so
the access to the duration is hidden behind a compatibility
API.

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/
- Don't use the source string length +1 as the size of the destination
(USD export & IMB_exr_get_handle_name).
- Correct undersized buffer being passed into imb_exr_insert_view_name.
