Now dragged handles are handled separately, and the function returns a
statically sized array by value. The functions are also renamed to be
more consistent with curve naming elsewhere in Blender.

This was only really used in one place, so better to just do it there
rather than requiring another argument for the handle calculation.

Previously for most materials (especially the ones without any
textures), the nodes were "off screen" way to the right, requiring
a view framing to even see them.
Also, as soon as multiple images were used, many nodes overlapped
one another and the connections were all a mess.
Simplify all that, and now each node type (coordinate, mapping, image,
normal map, bsdf etc.) is in it's own column, with BSDF at zero
coordinate. Each used image (along with any possible coordinate,
mapping, normal map) is it's own row. The resulting connections
are much cleaner.

This replaces the direct shader uniform layout declaration by a linear
search through a global buffer.
Each instance has an attribute offset inside the global buffer and an
attribute count.
This removes any padding and tighly pack all uniform attributes inside
a single buffer.
This would also remove the limit of 8 attribute but it is kept because of
compatibility with the old system that is still used by the old draw
manager.

Reversing Bezier handle types and positions would skip the middle point
of curves with an odd number of segments, which is still necessary to
swap in order to avoid changing the curve's shape.

This is a new implementation of the draw manager using modern
rendering practices and GPU driven culling.
This only ports features that are not considered deprecated or to be
removed.
The old DRW API is kept working along side this new one, and does not
interfeer with it. However this needed some more hacking inside the
draw_view_lib.glsl. At least the create info are well separated.
The reviewer might start by looking at `draw_pass_test.cc` to see the
API in usage.
Important files are `draw_pass.hh`, `draw_command.hh`,
`draw_command_shared.hh`.
In a nutshell (for a developper used to old DRW API):
- `DRWShadingGroups` are replaced by `Pass<T>::Sub`.
- Contrary to DRWShadingGroups, all commands recorded inside a pass or
sub-pass (even binds / push_constant / uniforms) will be executed in order.
- All memory is managed per object (except for Sub-Pass which are managed
by their parent pass) and not from draw manager pools. So passes "can"
potentially be recorded once and submitted multiple time (but this is
not really encouraged for now). The only implicit link is between resource
lifetime and `ResourceHandles`
- Sub passes can be any level deep.
- IMPORTANT: All state propagate from sub pass to subpass. There is no
state stack concept anymore. Ensure the correct render state is set before
drawing anything using `Pass::state_set()`.
- The drawcalls now needs a `ResourceHandle` instead of an `Object *`.
This is to remove any implicit dependency between `Pass` and `Manager`.
This was a huge problem in old implementation since the manager did not
know what to pull from the object. Now it is explicitly requested by the
engine.
- The pases need to be submitted to a `draw::Manager` instance which can
be retrieved using `DRW_manager_get()` (for now).
Internally:
- All object data are stored in contiguous storage buffers. Removing a lot
of complexity in the pass submission.
- Draw calls are sorted and visibility tested on GPU. Making more modern
culling and better instancing usage possible in the future.
- Unit Tests have been added for regression testing and avoid most API
breakage.
- `draw::View` now contains culling data for all objects in the scene
allowing caching for multiple views.
- Bounding box and sphere final setup is moved to GPU.
- Some global resources locations have been hardcoded to reduce complexity.
What is missing:
- ~~Workaround for lack of gl_BaseInstanceARB.~~ Done
- ~~Object Uniform Attributes.~~ Done (Not in this patch)
- Workaround for hardware supporting a maximum of 8 SSBO.

This was caused by un-wanted normalization. This is a requirement of
the MikkTspace. The issue is that g_data.N is expected to be normalized
by many other functions and overriden by bump displacement.
Adding a new global variable containing the interpolated normal fixes the
issue AND make it match cycles behavior better (mix between bump and
interpolated normal).

Since rB6269d66da, creating formats no longer depends solely on the
shader, but now depends on the dimensions used to fill the VBOs.
This allows 3D shaders to work flawlessly when assigned dimensions are
2D.
So there's no real benefit to us having shaders that are limited to 2D
use anymore.
This limitation makes it difficult to implement other builtin shaders
as they indirectly require a 2D version.
So this commit removes the 2D versions of the builtin sahders used in
Python , renames the string enums but keeps the old enums working for
backward compatibility.
(This brings parts of the changes reviewed in D15836).

To workaround that, we introduce a series of material flag that generates

Upcoming cryptomatte patch would need access to these defines. So moving
them from film_lib to shader shared. We cannot include the film_lib as
it requires images/textures to be bound that we don't need.
At the same time fixes incorrect casing (`lAYER` => `LAYER`).

GPUCapabilities expansion.
- Adding in compatibility paths to support minimum per-vertex strides for vertex formats. OpenGL supports a minimum stride of 1 byte, in Metal, this minimum stride is 4 bytes. Meaing a vertex format must be atleast 4-bytes in size.
- Replacing transform feedback compile-time check to conditional look-up, given TF is supported on macOS with Metal.
- 3D texture size safety check added as a general capability, rather than being in the gl backend only. Also required for Metal.

As pointed out in D15827 comment, the unique_ptr usage in
ShaderNodetreeWrap related code does not sound very useful. Looking at
it, whole ShaderNodetreeWrap does not make much sense - it's only
ever created, and then immediately just one thing is fetched from it.
This very much sounds like "a function", so make it just that -
header file contains just a `create_mtl_node_tree` function, and the
whole implementation is hidden from the users. Which I've also
simplified into just a handful of freestanding functions.
No functionality or performance changes, but the code does get ~80
lines shorter.
