Cycles: Use adaptive sampling division in the film kernel

Matches the pass data access in the buffers.cpp.

Unfortunately, the code is not currently running because there are no
adaptive sampling passes added to the viewport render.

Will work on enabling required passes in the viewport next.

Cycles: Fix adaptive sampling possibly being false enabled

Add an explicit check with the configuration rather than relying
on the sampling pattern.

Cycles: Remove unused adaptive sampling settings from KernelIntegrator

Cycles: Unify terminology/naming

Follow Cycles convention of using get/set as prefix.
This is the proper way ;)

Use correct add-ons branch for `make update`

Also add TODO comments, hoping they help us not forget changing this
back for the merge to master.

GPencil: Change UI name and icon for bezier pen

Cycles: Further improvements to the viewport rendering

The idea is to schedule more samples at a lower resolution, which
gives more usable visual feedback. For example, The Junk Shop scene
becomes a bit less resolution but is way less noisy (almost no black
pixels) while steel feeling interactive.

Currently schedule 4 samples during navigation, 2 samples for the
resolution which is the previous to the final one. When denoising is
enabled during navigation, schedule single sample (which makes it so
higher resolution will be rendered). This is because both denoisers
we have behave better on more noisy image but on higher resolution.

Additionally, lower the update rate in viewport. Non-trivial scenes
can not keep up 60fps without dropping resolution too much. So prefer
less often updates but have more clean updates during navigation.

Cycles: restore ray differentials in new integrator

Accept the extra memory usage for now, we'll try to compress these later.
This fixes bump mapping for more accurate comparisons.

Cycles: store ray differentials as scale instead of vector

For bump mapping at least this makes little visual difference, and reduces memory
usage and access cost on the GPU.

A further optimizations could also make the differentials in ShaderData smaller.

Ray differentials for NDC coordinates are disabled by this, to be brought back
later.

Fix missing object light visibility flags in new integrator

Do it as part of BSDF evaluation now, with advantage that we can skip evaluating
some BSDFs this way.

Fix wrong MIS weights leading to fireflies

Must keep track of distance to where the BSDF was sampled.

Fix subsurface scattering not working with bump mapping in new integrator

Fix wrong MIS weights for mixed BSDF and BSSRDF

GPencil cleanup: Fix compiler warning

Merge branch 'master' into temp-gpencil-bezier-stroke-type

Cycles: Fix transmission pass leaking into Combined

Was happening when there are transmission objects in the scene and the
transmission passes are not enabled. The pass offset in the KernelFilm
were left at 0, making it so `kernel_accum_light` believed the pass is
to be written, and the writing was happening into the combined pass.

Maybe we should initialize all passes offsets to PASS_UNUSED, so that
on an incorrect usage we'll have a memory error instead of silently
corrupting the combined pass?

This change fixes the startup file of myself, which is a glass monkey
on a plane.

Fix error on `context.copy()` because of asset-handle design

The File/Asset Browser no longer provides the `asset_handle` pointer. In
Python `asset_file_handle` needs to be used for now (will change in
future).

Assets: make `ASSET_OT_open_containing_blend_file` work in UIList

Make `ASSET_OT_open_containing_blend_file` in a asset view UIList as
well as the Asset Browser. This uses the context variables
`asset_file_handle` and `asset_library`, which are temporary in lieu of
a better asset API.
