initial replaceable unlinked inputs handler

Depending the use case, unlinked node inputs should be handled differently.
Sometimes, it is okay to load them from RNA on every call, but
sometimes they should also be hardcoded into the generated assembly.

T66266: Grease Pencil Simplify Adaptive is not behaving correctly

Now the simplify code works correctly in 3D space. Before it was trying
to project the strokes down into a local 2D space, but that didn't work
nicely for strokes with overhangs or big changes in the stroke
direction.

The code in question was simplified as well which lead to some nice code
reduction.

LANPR: Intersection cache now updates before lanpr_cache_finish().

Fix T63788: Crash if particle system is turned off in particle editing mode

Make sure particle system edit never points to a modifier or particle system
which becomes inactive.

This is needed because copy-on-write will change pointers of them and those
pointers are supposed to be restored from particle system evaluation. But
since the particle system is disabled it never updates pointers.

GreasePencil: Image render artifacts

When doing image rendering with grease pencil, it reused the view of
workbench or EEVEE. These views might be offsetted due to TAA.

This shifted the view a tiny bit. We will not reset the view in between
render engines.
