GPencil: Add missing update of modifiers

This was missing in previous commit for T66294

Fix Cycles session being (re)created twice

In most cases this only makes a small startup time difference, but there is
no reason to do this.

Cleanup: fix compiler warnings

Cleanup: avoid unnecessary primitive type lookup and variable initialization

Cycles: optimize Sobol loop

Ref D5363

Cleanup: add zero bit counting functions

Cycles: code to optionally zero initialize some structs in the kernel

This will be used by Optix to help the compiler figure out scoping. It is not
used by other devices currently, but worth testing if it helps there too.

Fix T69156: Blender crash when baking rigid body world.

Issue was exposed by recent own rB03bf84db86b commit, but was actually
present in RNA API for PointCaches since (probably) ages: whole accessor
code here was assuming that owner ID was an Object, when it is actually
a scene for RigidBody simulations...

Had also to make `BKE_ptcache_id_find()` and friends a bit more
flexible, now they also accept a NULL object pointer parameter...

GPencil: Invert Paste operator and make Paste to Active default

Before there were two options: Paste to original layer called "Paste" and Paste to active layer called "Paste & Merge"

Now, by default the paste is in active layer and the "Paste & Merge" has been renamed "Paste".

For old "Paste", now is called "Paste by Layer" and it's not the default value anymore.

Note: Minor edits to add icons not present in Differential revision.

cleanup arrayref and stringref

Fix T68826 Eevee: Multi-Mat not working if switching from Solid shading

The correct fix would be to avoid all those hacks but this is needed if
we want to be able to parallelize object vbo extractions.

This is the fixed version of the hack. The issue was that the ibo ranges
were saved before the batch were reset and the IBO was discarded, leading
to a read after free error. All previous reported crash were tested and
are now not reproductible.

Cycles: Fix Architecture logging on x64.

x64 builds with WITH_CYCLES_OPTIMIZED_KERNEL_SSE2 not defined
since SSE2 is the lower bar for x64 cpus. Turning the architecture
logging related if into the last if in the architecture detection
chain, which will never execute unless you turn off all kernels
in de debug flags.

Fix T69146: Segment Fault using Undo for file with several scenes and script.

The specifc bug here came fro; some IDProperties ID pointer storing
references to workspaces.

But that was actually a main loophole in that 'unndoing data while
keeping same UI' process, as we never know who might store a pointer to
one of those datablocks that we want to keep the 'old' version off.

It might actually be ever more needed when we start undoing (changing)
only the IDs actually modified in an undo step...

Notes:
* While not ideal, I think we can afford an extra looping over the whole
Main DB here... Remapping process in itself is fairly cheap, thanks to
the hashes.
* This commit is considered rather risky (especially thanks to 'private'
IDs), think it should work fine for now, unless some IDPointers start
storing references to private IDs...

Once D5559 is in, we shall do another pass here, probably also forbids
assigning private IDs to IDProperties, etc.

Cleanup: simplify perlin noise function definition
