Fix T72721: Add visibility flags updates to the PBVH

Currently, there its a function that sets manually the fully_hidden flag
of the nodes from the visibility operators in paint_hide.c. The undo
code was not updating the flag, so the visibility state of the nodes was
incorrect after preforming undo operations. This sometimes was drawing
fully hidden nodes with empty buffers, causing artifacts in the
geometry.

I added a function to mark nodes which visibility state changed (similar
as we are updating the mask flags and the nodes bounding boxes). This
way, the tools, operators and undo code don't have to update the
visibility flags, making everything much simpler to understand and
maintain.

I did not remove the flag update code from the current visibility
operators in this patch, but after reimplementing them (and all the new
ones) in the new visibility system, all visibility updates should be
done using this method and the BKE_pbvh_node_fully_hidden_set function
should be removed.

Cleanup: Constraints, simplified ChildOf evaluation function

This un-indents the `childof_evaluate()` function by one level, making it
easier to add new functionality in an upcoming commit.

No functional changes.

Cleanup: Reduced indentation in objectsolver_evaluate()

This will make an upcoming change cleaner to implement.

No functional changes.

Constraints: fixed Object Solver 'Clear Inverse' operator

The 'Clear Inverse' operator didn't properly update the constraint, so
it didn't do anything until the entire depsgraph was updated. It's now
properly tagged for update.

Tests: Constraints, enable layer collections before testing

In the collections unit test file developers can now disable layer
collections and declutter the 3D Viewport while working in
`constraints.blend`, without influencing the actual unit tests themselves.

Cleanup: Silence compilation warnings (unused variables)

Cleanup: Remove superfluous "cuda_device_ptr" function

Cleanup: removed runtime error

The render passes checked all bits of an integer, that can lead to
runtime errors. Added the max bit in the DNA and used this.

install_deps: fix several issues.

Lots of fixes and cleanups, mainly addressing:
* OpenEXR building was fully broken.
* Missing dependencies of Alembic to Boost and openEXR.
* OSL had changed its CMake parameters for custom OpenEXR install path.
* Dependencies between libs were not properly handles when switching a
lib from own build to system package.

EEVEE: First Buffer Drawn Incorrectly

SSS buffers are lazy initialized when needed. When shaders recompile the
SSS buffers could be incorrectly drawn. During the render passes project
we tried to fix this, but that resulted in incorrect result of the first
sample after a shader was compiled.

We revert this change knowing that we know the issue, but haven't found
a proper solution for it.

Cycles: Add option to change which sample to start viewport denoising at

This patch adds a new user-configurable option to change at which sample viewport
denoising should kick in. Setting it to zero retains previous behavior (start immediately), while
other values will defer denoising until the particular sample has been reached. Default is now
at one, to avoid the weirdness that is AI denoising at small resolutions.

UI: Add theme option for time markers line

This patch adds the ability to set colors and alpha of dashed line of
Time Markers. That way themes can avoid contrast issues and communicate
selection better. See screenshots in D6877.

GPU: Add Image property to allow high bitdepth support on a per image basis

This adds the `Half Float Precision` option in the image property panel.
This option is only available on float textures and is enabled by default.

Adding a flag inside the imbuf (IB_halffloat) on load is done for EXR and PSD formats that can store half floating point (16bits/channels).
The option is then not displayed in this case and forced.
