Geometry Nodes: update normals after transforming mesh

This is not done in `BKE_mesh_transform`.

Fix T80970: Copy Rotation constraint incorrect under shear

Orthogonalize the constraint target's matrix before decomposing it into
Euler angles. This removes sheer, and is actually a requirement for
correct decomposition.

It's conceivable that someone has used the incorrect behaviour in a rig.
As the shear caused unpredictable flipping of the constrained object,
this is unlikely.

Cleanup: clearer marking of what was changed in GTestAddTests.cmake

Replace `Blender` with `BLENDER` so that it's more clearly a marker, and
not just the name.

No functional changes.

Geometry Nodes: fix computing bounding box of evaluated point cloud

Currently, the bounding box does not include instances. This is consistent
with other object types.

macOS: Patch OpenImageIO's ustring for ARM.

OpenImageIO's ustring makes assumptions about the interals of
std::string which aren't true on macOS/ARM. A patch for OpenImageIO
addresses this for macOS/ARM builds only, at the expense of potentially
duplicated allocations of strings.

macOS: Added new location for Homebrew.

The build script for macOS dependencies expects to find bison provided
by Homebrew under /usr/local. Since the default install location for
Homebrew changes on macOS/ARM, the script now looks at the host
architecture and switches to /opt/homebrew on Macs with Apple Silicon.

Fix T81265: Animation is not evaluated when collection is included into view layer.

Just tag objects in un-excluded viewlayer for animation update.

Fix T82452: Outliner: Cyclic "Original ID" panel in Data API.

I cannot think of any case where we'd want to show this pointer in UI
anyway, so just tag it with `PROP_HIDDEN`.

fix missing params update in the scene BVH

a few more optimizations in OptiX

- avoid recreating temporary buffers for every builds
- avoid looking up the available memory when refitting, helps a lot in
files with lots of low-poly objects
- only allocate enough memory for the current build (build vs update)

Fluid: Updated Mantaflow source files

This update introduces two improvements from the Mantaflow repository:

(1) Improved particle sampling:
- Liquid and secondary particles are sampled more predictably. With all parameters being equal, baked particles will be computed at the exact same position during every bake.
- Before, this was not guaranteed.

(2) Sparse grid caching:
- While saving grid data to disk, grids will from now on be saved in a sparse structure whenever possible (e.g. density, flame but not levelsets).
- With the sparse optimization grid cells with a value under the 'Empty Space' value (already present in domain settings) will not be cached.
- The main benefits of this optimization are: Smaller cache sizes and faster playback of simulation data in the viewport.
- This optimization works 'out-of-the-box'. There is no option in the UI to enable it.
- For now, only smoke simulation grids will take advantage of this optimization.

UI: Allow theming the alternate row color in the sequencer

Previously, the alternate row color in the Video Sequence Editor was
just a shaded version of the editor's background color. This makes it
theme-able just like in the file browser and outliner, although the
default color is very slightly different.

Fix Edit Face Set operator not being cancelled when the cursor is not over the mesh

If the cursor is not over the mesh, the operator was still using the
last Face Set ID updated by the drawing cursor code when the cursor was
over the mesh.

This now cancels the operator instead of modifying a Face Set that will
look random to the user.

Rename use paint symmetry to use mesh symmetry in quadriflow

The original name was chosen because symmetry was a property of
the Paint struct. Now symmetry is a property of meshes, which
also makes the name of the property easier to understand.

Geometry Nodes: Node editor header interaction with active modifier

This commit makes the way the selector in the middle of the node editor
header interacts with the active modifier much more intuitive.

- With no active modifier, or when the active modifier is a non-node
modifier, the "new" operator adds a new nodes modifier.
- With an active node modifier, the drop-down affects the modifier's
selected node group.
- With no active object, there is no drop-down in the header.
- The node editor's node group always updates, even when there is no
active modifier.
- Pinning disables the drop-down and keeps the same node group
selected, regardless of the context.

This is designed to work similarly to materials and material slots,
which should be familiar to any Blender user. One workflow not allowed
by this design is editing any geometry node group, regardless of the
context, but if that turns out to be an issue it should be solved in a
similar way for all node editors.

Cleanup: Typo in `print_default_info` function name.

Fluid Particles: fix viscoelastic spring threading crash again after D7394.

Since D6133 fluid particle code uses thread local storage to collect
springs created during a time step before adding them to the actual
spring array.

Prior to the switch to TBB there was a single finalize callback which
was called on the main thread, so it could use psys_sph_flush_springs
and insert the new entries into the final buffer. However in D7394 it
was replaced with a reduce callback, which is supposed to be thread
safe and have no side effects. This means that the only thing it can
safely do is copy entries to the other temporary buffer.

In addition, careful checking reveals that the 'classical' solver
doesn't actually add springs, so reduce isn't needed there.

Geometry Nodes: Improve wording of modifier error messages

- Don't use contractions
- Remove unecessary words
