Remove math for 2D affine transform

Commit e1665c3d3190 added math to do 2D affine transformations with 3x3
matrices, but these matrices are also used for 3D transformations.

Remove added functions and use 4x4 matrices for 2D transformation.

Fix versioning for sequencer color balance modifier.

Commit 213554f24a17 added slope/offset/power controls to the sequencer
color balance modifier, but colors in this mode were not initialized
with old files.

Initialize colors to default values.

Sculpt: smothing ops now slide UVs

* Wrote a new function, SCULPT_reproject_cdata,
to reproject loop customdata after smoothing.
* SCULPT_reproject_cdata is only called if UV
layers exist.
* All of the smoothing tools (hopefully all)
use it.
* This change is necassary to properly support vector
displacement maps in the future; otherwise DynTopo
will introduce lots of noise into the uv tangent
space.

Cleanup: remove unused functions

Fix T72583: Sun Beams node artifacts

The artifacts are due to the loss of precision when doing some
calculations with float precision.

Geometry Nodes: Updated Subdivision Surface Node

Replaces the old Subdivision Surface Node.

Changes:
- Removes implicit instance realization, instead the node runs once
per unique instance.
- "Use Creases" becomes a crease field input applied to edges.
The values are clamped between zero and one.

Geometry Nodes: Object info node optional instance output

The object info node output an instance as a performance optimization.
Before that optimization was (almost) invisible to the user, but now
that we aren't automatically realizing instances, it isn't intuitive
for a single object to become an instance.

I refactored the transform node so its ability to translate/transform
an entire geometry set was more usable from elsewhere and exposed the
function to get a geometry set from an object.

Geometry Nodes: Fields transfer attribute node

This commit adds an updated version of the old attribute transfer node.
It works like a function node, so it works in the context of a
geometry, with a simple data output.

The "Nearest" mode finds the nearest element of the specified domain on
the target geometry and copies the value directly from the target input.

The "Nearest Face Interpolated" finds the nearest point on anywhere on
the surface of the target mesh and linearly interpolates the value on
the target from the face's corners.

The node also has a new "Index" mode, which can pick data from specific
indices on the target geometry. The implicit default is to do a simple
copy from the target geometry, but any indices could be used. It is also
possible to use a single value for the index to to retrieve a single
value from an attribute at a certain index.

Cleanup: Refactor use of implicit inputs in geometry nodes

Instead of checking whether the socket value was hidden, use the proper
node declaration to check whether the socket has an implicit input. The
remaining larger change to make is allowing nodes to specify what their
implicit input should actually be.

Fix: Field type inference considers unavailable sockets

If a node had unused/unavailable inputs, they were still considered
when deciding whether the output is a field or not.

UI: Remove extra padding around curve widget

This commit removes the constant padding around to the left and
right of the curve widget. The padding worked in screen space and
didn't take UI scale/zoom into account. This makes the curve widget
consistent with the more recently added curve profile widget used
for bevel profiles.

Fix T62325, T91990: changing Cycles presets does not update the Blender UI

Checking RNA_MAGIC is not enough to identify the ID property case which always
needs updates. If the property is already resolved to an RNA property we need
to check the flag too.

Asset Browser: Hide Import Types menu for "Current File" asset library

This menu doesn't have an effect on the importing while in the "Current File"
asset library. This can be quite confusing.

However, just hiding the menu may be a temporary solution. Decision
actually to instead show a different menu, that allows choosing between
duplicating and reusing data on drop. This is being reviewed here
https://developer.blender.org/D12879.
Meanwhile (or in case we end up rejecting that), this change should
avoid some confusion.

Fix T92032: Cycles panoramic cameras do not support shift

Fix T92083: Crash renaming bone used in Armature modifier on curve

This is caused by {rB3b6ee8cee708}.

Since rigging curves with armatures only works with envelopes (if I am
not mistaken), this stirs up the question again why we actually give the
choice for vertex groups in parenting. Anyways, curves can have armature
modifiers and renaming bones should not crash.

Now make sure we only go down the route of `BKE_object_defgroup_list`
and `BKE_object_defgroup_find_name` if vertex groups are actually
supported.
