Fix T89366: GPencil hide layers above parented layer

The problem was the flag was not reset by layer in the loop.

Pushed all thumbnail rendering and caching code to new function. Cleaned up
all conditions using context->is_thumb.

Fix T89343: Point cloud instances not transformed when realized

This problem has surprisingly been there for quite a few months.
For point clouds all attributes were handled the same, even "position",
which should be transformed when combining source points into the
destination.

Revert "Enhanced stats/reports for blendfile reading."

This change crashes library linking operators, related tests and probably more.

This reverts commit f8d219dfd4c31a918e33cb715472d91a5cd3fd51.

Ref D11583

Geometry Nodes: Join curve attributes when realizing instances

Previously the code assumed that curve instances had no attributes.
This is true when the data came from curve objects, which don't support
attributes currently, but it isn't necessarily true when retrieving curves
from evaluated geometry sets.

Cleanup: Refactor spline copying functions

Make the virtual functions protected and simpler, so that the logic is
better contained in the base class's implementation. Also introduce a
`copy_without_attributes` method to be used for realizing instances.

Fix deadlock with shrinkwrap and other modifiers

More code that needs task isolation. Encountered in sprite fright production
file.

Ref D11603

adaptive_cloth: mesh_reader: obj parse

Enhanced stats/reports for blendfile reading.

Add direct user feedback (as a warning report) to user when recursive
resync of overrides was needed.

And some timing (as CLOG logs) about main readfile process steps.

This is essentially adding a new BlendFileReadReport structure that wraps
BKE_reports list, and adds some extra info (some timing, some info about
overrides and (recursive) resync, etc.).

Organize USD and Alembic conditional includes.

Grouped common USD and Alembic mesh sequence cache code includes.

LineArt: Move type rejection before visibility check

LineArt: Move type rejection before visibility check

Minor cleanup to previous commit introducing `BLI_math_time`.

Forgot to address latest review comments, sorry for the noise.`:wq

Add initial `BLI_math_time` with a 'seconds decompose' function.

Allows to decompose a given amount of seconds into a random set of
days/hours/minutes/seconds/milliseconds values.

Also add matching test.

Animation: allow specifying a custom frame range for actions.

Some operations, e.g. adding a new action strip to NLA, require
knowing the active frame range of an action, but currently it can
only be deduced by scanning the keyframes of the curves within it.
This is not ideal if e.g. curves are staggered for overlap.

As suggested by Nathan Vegdahl, this patch adds Action properties
that allow manually specifying its active frame range, and whether
it is intended to be cyclic. The settings are exposed in a popover
in Action Editor. When enabled, the range is highlighted in the
background using a striped fill to distinguish it from the solid
filled regular playback range.

When set, the frame range is used by NLA. In addition, the Cycle-Aware
Keying option automatically sets up F-Curves newly added to a cyclic
action to use cyclic extrapolation with the correct period.

Animation: support filtering for curves with a cycle period mismatch.

Since the looping behavior is defined per curve rather than at
action level, it is possible for curve loop periods to get out of
sync with each other. This commit adds an option to compare curves
against the frame range specified in the action, and treat those
with a mismatch as errors for the purpose of F-Curve filtering.

When enabled, the check verifies that curves within the action
have valid cyclic extrapolation, and the action period evenly
divides by the curve period (since a curve looping at e.g. half
of the action period length still repeats in sync with the action).

Temporary Hack: provide B-Bone scale versioning for files with old patch.

Run the versioning code for the conversion of bbone scale to an xyz
vector if it has fields that correspond to the old version of the
patch before that change requiring versioning.

The actual Y (length) scale value from the old patch isn't versioned
and will be lost, requiring manual fixing.

Bone Overlay: support bone wireframe opacity settings.

When weight painting the bone overlay is extremely intrusive,
effectively requiring either extensive use of hiding individual
bones, or disabling the whole bone overlay between selections.

This addresses the issue by adding two bone opacity sliders that
are used for the 'wireframe' armature drawing mode. One directly
controls the opacity in a uniform way. The other one allows fade
based on the depth between the near and far clip planes in order
to provide an automatic visual cue about which bones are closest.

Constraints: refactor the D7437 patch adding Custom Space for constraints.

As mentioned in the comments to that patch, I had an idea for
a different way to do some technical aspects, but it was too
complicated to force changes in the original patch. Thus I submit
this follow up patch.

First, instead of modifying all the get_constraint_targets and
flush_constraint_targets callbacks, introduce wrapper functions
for accessing constraint targets, convert all code to use them,
and handle the new reference there uniformly for all constraints.

This incidentally revealed a place in the Collada exporter that
didn't clean up after retrieving the targets.

Also, tag the special target with a flag so other code can
handle it appropriately where necessary. This for instance
allows dependency graph to know that the Use B-Bone Shape
option doesn't affect this specific target.

Finally, rename and simplify the function for initializing the
custom space, and make sure it is called everywhere necessary.

Constraints: support a new Local Space (Owner Orientation) for targets.

Add a new transformation space choice for bone constraints, which
represent the local transformation of the target bone in the constraint
owner's local space.

The use case for this is transferring the local (i.e. excluding the
effect of parents) motion of one bone to another one, while ignoring
the difference between their rest pose orientations.

Owner Local Space replaces the following setup:

* A `child` bone of the `target`, rotated the same as `owner` in rest pose.
* A `sibling` bone of the `target`, positioned same as `child` in rest
pose and using Copy Transforms in World Space from `child`.
* The `owner` bone constraint uses Local Space of `sibling`.

(This analogy applies provided both bones use Local Location)

Since the space list is getting long, also add a couple of separators.
