Fix T91607: GPencil Tint modifier "apply" removes the effect

BLI: support initializing empty FunctionRef with nullptr

This may sometimes be desired because it is more explicitely
shows that the `FunctionRef` will be empty.

Cleanup: add using declarations

BLI: avoid warning when copying empty StringRef

BLI: initialize MutableSpan in default constructor

Geometry Nodes: fix evaluating field to span

Cleanup: Themes: Remove invalid theme option

`font_kerning_style` was removed in rBa1e91fbef3dc9a5d5c8456cd9a887aac1bdb652c

Fix T91608: Cycles crash with tile size 0

UI: Add description for Batch rename

Added description for Batch rename which pop-ups when
hovering the mouse over "Batch rename" inside the edit menu.

Fix T91592: Negative Cycles remaining render time

For the default startup was showing -14:-08.-48 as a remaining time.

Was an integer overflow when specifying total number of pixel-samples.

Fix T91603: Cycles crash when volume becomes visible

Making object which uses volume shader invisible will mark the shader
as not having a volume, forcing re-compilation of the shader to bring
it back to a consistent state.

The compilation is happening as part of scene update, which needs to
know kernel features. So there is a feedback loop.

Use more relaxed way of knowing whether there is a volume in the
shader for the kernel features, which doesn't require shader to be
compiled first.

Solves issues from the report, but potentially causes extra memory
allocated if the volume part of graph is fully optimized out. This
downside is solvable, but would need to split scene update into two
steps (the one which requires on kernel, and the one which does not).
It will be an interesting project to tackle, but for a bug fix is
better to use simpler solution.

Fix T91576: Cycles attribute node with name N for smooth normal no longer working

There was an optimization to remove duplicate storage of normals as attributes
when using normal maps. However for named attributes like this we still need to
store the attribute.

Don't request normal attribute from the normal map node now, instead of skipping it
in the geometry code.

GPencil: Fix unreported missing material panel for new Scene

When a new scene is created, the paint pointers are not available before using them, so the python panel exits because the pointer was None.

Now, the pointer is checked in order to display the materials panel as expected.

Initial implementation of local ID re-use when appending.

This commit adds to ID struct a new optional 'weak reference' to a
linked ID (in the form of a blend file library path and full ID name).

This can then be used on next append to try to find a matching local ID
instead of re-making the linked data local again.

Ref. T90545

NOTE: ID re-use will be disabled for regular append for the time being
(3.0 release), and only used for assets. Therefore, this commit should
not change anything user-wise.

Cleanup: make format

Geometry Nodes: Curve Fillet Node

This node can be used to fillet splines at control points to
create a circular arc.
The implementation roughly follows T89227's design.

The node works in two main modes: Bezier and Poly
* Bezier: Creates a circular arc at vertices by changing
handle lengths (applicable only for Bezier splines).
* Poly: Creates a circular arc by creating vertices (as
many as defined by the Count fields input) along
the arc (applicable for all spline types).

In both modes, the radius of the created arc is defined
by the Radius fields input.
The Limit Radius attribute can be enabled to prevent
overlapping when the defined radius exceeds the maximum
possible radius for a given point.
