Adds support for generating curve primtiives avoiding the
use of primtiive restarts. This maixmises geometry performance
when using Metal.
Also ensure that the existing index buffer optimization path is
skipped for indirect draw calls where counts are not known at
submission time.

PixelBuffer required addition of buffer re-allocation during mapping
to avoid host updates over-writing previous in-flight data as required
by the GPU. Changes allow multiple copies of existing pixel data to
be in-flight simultaneously.

This replaces the Sheen model used in the Principled BSDF with the
model from #108869 that is already used in the Sheen BSDF now.
The three notable differences are:
- At full intensity (Sheen = 1.0), the new model is significantly
stronger than the old one. For existing files, the intensity is
adjusted to keep the overall look similar.
- The Sheen Tint input is now a color input, instead of the
previous blend factor between white and the base color.
- There is now a Sheen roughness control, which can be used to
tweak the look between velvet-like and dust-like.

The cleanup of blenkernel last weeks , caused the house of cards to
collapse on top of bf_gpu's shader_builder, which is off by default
but used on a daily basis by the rendering team.
Given the fixes forward in #110394 ran into a ODR violation in OSL that
was hiding there for years, I don't see another way forward without
impeding the rendering teams productivity for "quite a while" as there
is no guarantee the OSL issue would be the end of it.
the only way forward appears to be back.

The problematic commit was 07fe6c5a57
as blenkernel links most of blender, it's a bit of a link order issue
magnet. Given all these commits stack, it's near impossible to revert
just that one without spending a significant amount of time resolving
merge conflicts. 99% of that work was automated, so easier to just
revert all of them, and re-do the work, than it is to deal with the
merge conflicts.

Implements part of #101689.
The "poly" name was chosen to distinguish the `MLoop` + `MPoly`
combination from the `MFace` struct it replaced. Those two structures
persisted together for a long time, but nowadays `MPoly` is gone, and
`MFace` is only used in some legacy code like the particle system.
To avoid unnecessarily using a different term, increase consistency
with the UI and with BMesh, and generally make code a bit easier to
read, this commit replaces the `poly` term with `poly`. Most variables
that use the term are renamed too. `Mesh.totface` and `Mesh.fdata` now
have a `_legacy` suffix to reduce confusion. In a next step, `pdata`
can be renamed to `face_data` as well.

This was already unsupported in combination with Multiscattering GGX,
prevented the Principled BSDF from using microfaced-based Fresnel for
Glass materials, and would have made future improvements even trickier.

The maximum OpenGL versions supported on mac
doesn't meet the minimum required version (>=4.3) anymore.
This removes all the OpenGL paths in GHOST
Cocoa backend and from the drop down menu in
the user preferences.

Previously the normal strength linearly interpolated and extrapolated
the normal in world space. Instead do it in tangent space, in a way
that ensure the normal remains above the surface and valid.

No user visible changes expected, the new button state is not used yet.
Setting a new uiBut drawflag shows items in an indeterminate state, not

This removes the GL 3.3 fallback because default viewport engine
now require some features only present in GL 4.3.
Blender now also check for GL version 4.6 instead of 4.5 in some
cases.
Note that this does not remove the OpenGL support on Apple
hardware.

Certain feature requirements unsupported by older OS builds
caused failures when running Intel GPUs on older OS's.
This patch increases the minimum required OS version
to one which covers devices supporting all required features.

The Voronoi distance output is clamped at 8, which is apparent for distance
metrics like Minkowski with low exponents.
This patch fixes that by setting the initial distance of the search loop to
FLT_MAX instead of 8. And for the Smooth variant of F1, the "h" parameter is set
to 1 for the first iteration using a signal value, effectively ignoring the
initial distance and using the computed distance at the first iteration instead.

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.
