Geometry Nodes: Add geometry instances data to the spreadsheet

This patch adds data about instances generated by geometry nodes
to the spreadsheet. The transform data is decomposed into position,
rotation, and scale, and there is a name column to display the name
of the instanced object or collection.

This data is implemented specifically for the spreadsheet, because
we're not sure that we want to expose this data as attributes for the
use elsewhere.

BLI: Add accessors for translation, rotation, and scale of float4x4

Cleanup: rename x1/x2/y1/y2 to x/y/width/height

Geometry Nodes: Refactor / fix point separate node

The point separate node was failing in situations where one of the
outputs was empty. In addition, the code was not structured very well.
This new implementation stores less temporary information, is more
geometry component type agnostic, and is more self-descriptive.
It also solves the problems mentioned above.

Cycles: Avoid temporary buffer allocation for GPUDisplay update on CPU

The idea is to request GPUDisplay to map memory, so that the film
conversion can happen directly into that memory.

Additionally, move away from task to a kernel call.

In an own tests here the full viewport render time on a very simple
file is now about 6% faster, although is unclear whether it is due
to TBB or due to avoiding extra memory copy. Still nice.

The GPU part still needs work, and will be handled separately.

Cycles: Make buffer parameters more coupled to PathTraceWork

It is annoying to pass scaled parameters to every call. More correct
approach it seems to be to make them more "sticky": they become a
property of path trace work, together with the render buffers.

The idea is to have the following in the long term:
- PathTrace allocates render buffers for every PathTraceWork
- PathTrace updates parameters of every PathTraceWork on resolution
divider change.
- PathTrace re-allocates the buffer when balancing is needed to
accomodate for performance difference of different render devices.

This way PathTraceWork always knows its buffer pointer and effective
parameters and always uses them in all the API calls.

LineArt: Added back the missing "allow_clipping_boundaries" option.

This option was missing from the UI.
Also add missing camera settings depsgraph relation.

LineArt: Modifier defaults settings optimization.

Make options that are usually only useful in edge cases off by default.
These settings would requite extra work and thus the modifier evaluation
would be needlessly slower as most users do not need these options to be
on.

LineArt: Remove geometry space chaining

It caused some chaining errors when used in combination with image space
chaining. After some internal discussion, we realized it is not
useful as chaining in image space essentially does the same thing.

Cycles: Avoid explicit CPU-side buffer in GPUDisplay

The idea is to use OpenGL texture and pixel buffer object
to push pixels from PathTrace to the GPU for draw.

The need of the PBO is because updating texture from the
copy_pixels_to_texture() function turned out to be quite
expensive in terms of CPU time spent, degrading viewport
render performance. The downside of this approach is that
the peak memory might be higher when rendering on a multiple
devices compared to partial direct texture updates. Although
this is hard to tell for sure, since it depends on exact way
of how driver schedules updates and manages memory.

The upside of this change is that it makes it so PBO is
there, ready to be used by CUDA's GL graphics for direct
update without CPU memory round-trip.

The performance is a bit hard to measure, since the timing
varies quite a bit, but on the CPU it is the same ballpark.

Draw manager: Add utility functions for context creation

Some special logic is needed to release the active DrawManager OpenGL
context when new context needs to be created by a render engine.

This change introduces functionality which is needed for such process,
including a simple example usage in the comment.

Small cleanup

Larger width for name column, use values for object and collection specifically
