Cycles: Remove unused CMJ enum

Cycles: De-duplicate average time reset logic

Cycles: Keep track of average GPU display update time

Cycles: Improve start resolution calculation

Take denoising and display update times into account.

Additionally, lower update interval when denoising will happen on
a scaled down render. This way denoiser have more pixels to work
with, avoiding a blurry mess in the cost of less interactive
navigation.

Cycles: Unify device variable name

Just stick to a commonly used `device`. The original idea of making it
clear that the device is actual a compute (non-multi) device didn't
really work that great.

Cleanup: Extra spaces at the end of comment

Cycles: Enable all passes for OpenImageDenoiser

Finishes the OpenImageDenoiser re-implementation to the same feature
level as it was before the big refactor.

GPencil: Add Bezier support to Lattice modifier

GPencil: Add Bezier support to Array modifier

Pose Library: correct status text when blending poses

Pose Library: remember last-used blend factor

When the interactive blending operator finishes, store the chosen blend
factor in the RNA properties. This ensures that pressing F9 shows the
actual factor, which can then be readjusted.

Cycles: restore writing of light render passes

* Write directly into render buffers instead of PathRadiance
* Indirect and shadow paths are now marked as needing to be written to either
reflection, transmission or volume scatter passes with a flag
* For diffuse/glossy distinction in reflection, we store the ratio of diffuse
and glossy so we can reconstruct the diffuse and glossy throughput
* Get rid of ShadowLight integrator state store in shadow path throughput and
flag instead

Still missing:
* AO and shadow passes
* Proper handling of ray visibility on lights
* Adaptive sampling passes

A bit of progress

Pose Library: cleanly stop blending when quitting Blender

When Blender quits while the pose blending operator is active, set the
correct state (`POSE_BLEND_CANCEL`) before exiting, so that cleanup done
correctly.

Asset Browser: monitor subprocess after opening new Blender

Monitor the new blender subprocess from the "Open Blend File" operator,
and reload the asset browser after the subprocess stops.

Asset Browser: add "Open Blend File" operator to Asset browser context menu

Add an "Open Blend File" operator to the Asset Browser context menu,
which starts a new blender process to open the blend file containing the
active asset.

Pose Library: remove use of `BONE_UNKEYED` bone flag

This bone flag was removed in rBfd10c21f51243921e645939e3f6a569c19864d8e.

No functional changes.
