Fix T74254: EEVEE Render Passes Availability

When disabling AO or BLOOM in the render tab, when the pass is shown in
a 3d viewport the pass wasn't reset. This resulted in showing a black
texture and a not filled UI render pass in the shading popover.

This patch will by default reset to the combined pass. It is intended
that the render_pass in the 3d shading struct isn't set to combined as
people could have disabled AO/bloom by mistake and it could reset
viewports that aren't visible.

Fix T74227: Crash when clicking on viewport shading properties

Fix T71743: NLA editor doesn't update properly when hiding/viewing objects

The NLA area & region listeners were ignoring the notifications that happen
when hiding/showing objects & collections.

Fix T69576, T74059: issues with rotation when adding objects

This clarifies logic in ED_object_add_generic_get_opts (see comments in
code).

Also following issues are adressed:
- do not enforce setting the op UI to WORLD when rotation is set (e.g.
on redo). This is not wrong (happens in world space), but is more
confusing than helpful (was added in own rB3b8a14a3c072).
- respect setting the User Preference to WORLD properly (could fail when
set to something else, then back to WORLD)

Constraints: replace 'Set Inverse' operator with an eval-time update

This fixes {T70269}.

Before this commit there was complicated code to try and compute the
correct parent inverse matrix for the 'Child Of' and 'Object Solver'
constraints outside the constraint evaluation. This was done mostly
correctly, but did have some issues. The Set Inverse operator now defers
this computation to be performed during constraint evaluation by just
setting a flag. If the constraint is disabled, and thus tagging it for
update in the depsgraph is not enough to trigger immediate evaluation,
evaluation is forced by temporarily enabling it.

This fix changes the way how the inverse matrix works when some of the
channels of the constraint are disabled. Before this commit, the channel
flags were used to filter both the parent and the inverse matrix. This
meant that it was impossible to make an inverse matrix that would
actually fully neutralize the effect of the constraint. Now only the
parent matrix is filtered, while inverse is applied fully. As a result,
pressing the 'Set Inverse' matrix produces the same transformation as
disabling the constraint. This is also reflected in the changed values
in the 'Child Of' unit test.

This change is not backward compatible, but it should be OK because the
old way was effectively unusable, so it is unlikely anybody relied on
it.

The change in matrix for the Object Solver constraint is due to a
different method of computing it, which caused a slightly different
floating point error that was slightly bigger than allowed by the test,
so I updated the matrix values there as well.

This patch was original written by @angavrilov and subsequently updated
by me.

Fix T54323: Improve Paint category names in keymap preferences

While one issue of the report was fixed already (rB27adc4aa3347), still a
couple of clarifications could be made:
- correct/clarify which modes these apply to
- clarify that "Face Mask" is a paint thing

Fix Vertex weight gradient tool show wrong weight/strength values in the
UI

Main issue is that the UI doesn not respect the Unified Weight/Strength
setting (but instead alwasy shows the brushes weight/strength)

Was working before, but somewhat missed in rBfb74dcc5d69d.

See discussion in T74025 on why the Gradient Tool in its current state
is not very user friendly in general, what I think we should do though
is at least have the values in the UI respect Unified Weight / Unified
Strength since this is what the tool will use internally...

Fix OpenVDB link error on Windows after recent changes

Cleanup: split image sequence detection into own file, and make it reusable

Color Management: Updated False Color Look

Change to false color are based on artist feedback:

* Even 2.5 EV differences down to -10 EV.
* Even 2.167 EV differences up to +6.5 EV.
* Slightly below middle grey biased toward cyan.
* Slightly above middle grey biased toward yellow.
* Converts to nonlinear luma for more accuracy.

Color Management: Allow looks on any transform

Previously it was not possible to use looks on filmic log.

Cleanup: add ImageKey to avoid longer argument lists and duplicated code

Cleanup: deduplicate OpenVDB library definitions/include/libs logic

This will more important when we start using OpenVDB in more modules.

Build: add compatibility between precompiled libraries and new glibc

On Linux, precompiled libraries may be made with a glibc version that is
incompatible with the system libraries that Blender is built on. To solve
this we add a few -ffast-math symbols that can be missing.
