Fix T89390: crash when join geometry node has only muted inputs

Workaround for assert from 27da305a404f72a75a37892e1ac080c6531d059b

This worked for existing scenes but adding new objects was asserting
needs further investigation.

Depsgraph: support flushing parameters without a full COW update

Avoid computationally expensive copying operations
when only some settings have been modified.

This is done by adding support for updating parameters
without tagging for copy-on-write.

Currently only mesh data blocks are supported,
other data-blocks can be added individually.

This prepares for changing values such as edit-mesh auto-smooth angle
in edit-mode without duplicating all mesh-data.
The benefit will only be seen when the user interface no longer tags
all ID's for copy on write updates.

ID_RECALC_GEOMETRY_ALL_MODES has been added to support situations
where non edit-mode geometry is modified in edit-mode.
While this isn't something user are likely to do,
Python scripts may change the underlying mesh.

Depsgraph: remove redundant mesh data duplication in edit-mode

This resolves a bottleneck where every update while transforming
copied the entire mesh data-block, which isn't needed as the edit-mesh
is the source of the data being edited.

Testing shows a significant overall speedup when transforming:

- ~1.5x with a subdivided cube 1.5 million vertices.
- ~3.0x with the spring mesh (edit-mode with modifiers disabled,
duplicated 10x to drop performance).

Fix T87486: Can't open file with modifiers to a grease pencil library override

Very stupid typo in override apply code on GP modifiers (typical
copy/paste mistake from original modifiers code).

@jbakker this should be back-ported to 2.93LTS.

Fix linking code after own recent commit.

More stupid mistake in recent enhanced reports for file load code,
rB82c17082ba0e left some read-after-free situations.

CMake: link bf_blenkernel from bf_depsgraph

Without this tests fail to lknk in D11377. Commit separately as the
depsgraph is using BKE it should link to it.

Cleanup: update clang-format so PyObject_HEAD indents properly

Cleanup: clang-format, spelling

Cleanup: remove outdated/redundant comments

Cleanup: use '#if 0' for commented code-block

LineArt: Bound box visibility check when loading

This patch enables bound box check when loading geometry
into line art. Works with overscan as well. Will discard
object if its bbox completely lies in one side of the
clipping space frustum.

Line Art: Discard out of frame edges.

For scenes that have a lot of edges, this could potentially
save some time generating individual strokes that are outside
camera frustum.

Fix failure when baking actions with Bendy Bones

682a74e0909ba renamed Bendy Bones properties and replaced existing float
properties with float-vector properties. This updates the property names used
by the action baking operator (`NLA_OT_bake`).

Remove window iteration in WM_DISPLAYCHANGE.

Iteration was incorrectly calling the same object. Had it called every
window it would still be unnecessary as WM_DISPLAYCHANGE is sent to all
broadcast receiving windows.
