Fix T92930: Outliner "Show Active" bone fails in certain situations

Outliner would frame the armature object instead of the bone if the bone
was on a hidden armature layer.

Similar to issues reported in e.g. T58068 and T80464, this is due to the
fact that `BKE_pose_channel_active` always checks for the armature layer
(and returns NULL if a bone is not on a visible armature layer).

Now propose to make this layer check **optional** (and e.g. from the
Outliner be more permissive). This also introduces
`BKE_pose_channel_active_if_layer_visible` which just wraps
`BKE_pose_channel_active` with the check being ON.

Tests: initialise BKE callbacks before loading blend file

Initialise the BKE callback system in
`BlendfileLoadingBaseTest::SetUpTestCase()`. This allows certain tests
to run in debug mode (when `BLI_assert` is enabled).

Fix T93757: Do not force-instantiate indrectly linked objects in linking case.

Fix T93839: Copy/Paste of empty instantiating a collection.

Do not also instantiate a collection in the view layer, if it is already
instantiated through an empty object.

Fix build error in debug builds from recent commit

r7acd3ad7d8e58b913c5 converted a pointer to a reference,
but an assert still compares the variable to a pointer.

Fix T94280: Crash when splitting meta strip

This happens because in `SEQ_time_update_sequence` function
`SEQ_get_meta_by_seqbase` returns uninitialized value. This isn't nice,
but it shouldn't happen in first place. Problem is, that
`SEQ_edit_strip_split` does move strips into detached `ListBase`, so
other functions can't see them anymore. Detached `ListBase` is used
solely to preserve relationships during duplication.

Move strips to original `ListBase` immediately after duplication and
return `NULL` if `SEQ_get_meta_by_seqbase` can't find meta strip.

Splitting itself can still rely on fact, that number of original and
duplicated strips is same and they are placed next to each other in
exactly same order at the end of original `ListBase`.

Cleanup: Use span instead of raw pointer

This is a followup to the previous commit.

Cleanup: Use simpler loops in weld modifier

In this commit I changed many loops to range-based for loops.
I also removed some of the redundant iterator variables, using
indexing inside the loop instead. Generally an optimizing compiler
should have no problem doing the smartest thing in that situation,
and this way makes it much easier to tell where data is coming from.

I only changed the loops I was confident about, so there is still more
that could be done in the future.

Fix T94262: Grease Pencil Blur Effect DoF mode wrong

This was visible outside of camera view and was not respecting the
"Depth of Field" checkbox on the Camera properties.

Now return early if DoF should not be visible.

Sculpt: split sculpt.c into three files

Sculpt.c is now three files:

* Sculpt.c: main API methods and the brush stroke operator
* Sculpt_brushes.c: Code for individual brushes.
* Sculpt_ops.c: Sculpt operators other than the brush stroke operator.

TODO: split brush stroke operator into a new file (sculpt_stroke.c?).

Fix T94144: Duplicate edges in dual mesh node

The duplicated edges were caused by 'oversubdivided' edges, i.e. edges
where some of the vertices on them are only connected to two polygons.
The fix finds these vertices and 'dissolves' them so that only one edge
is created.

For most 'normal' meshes this shouldn't occurr, or only very little, so
the performance impact of this change should be neglegible. In practice
this is also avoidable by triangulating the mesh first.

Cleanup: Remove mesh valid assertions in debug builds

These are useful for development, but when the primitive nodes
aren't actively changing, the performance cost is not worth it.

Fix: Incorrect assert conditions in NURBSpline

This fix provides better conditions for asserts in `NURBSpline::knots`
method accounting for cyclic NURBS curves.

Cleanup: Remove unused node type flag

This flag was checked, but not set anywhere.

Cleanup: Comment formatting in node.cc

Also remove a SCOPED_TIMER I added by mistake in a previous commit.

Geometry Nodes: Parallelize mesh grid primitive

On a Ryzen 3700x, this ended up 2.5x faster than before. More
benchmarking details are included in the differential revision.

For smaller grids, all this should do is increase the
code size a bit, and add a few more if statements.

Cleanup: Remove unused arguments

Update our USD 21.02 patch to support gcc-11

There are two issues in USD code that break building it with gcc-11,
one (in `demangle.cpp`) was already fixed upstream, the other (in
`singularTask.h`) is still pending (reported upstream, see
https://github.com/PixarAnimationStudios/USD/issues/1721).
