Replace `const char *` with `StringRef` for the API in `BKE_attribute.h`.
The benefits are slightly simpler code and possibly slightly improved
performance through avoiding the need to measure string length.

Adds new function `foreach_content_slice_by_offsets` that gathers mask's
indices into `IndexRange` lists grouped by given offsets. New approach
doesn't need temporary `points_to_duplicate` array of size
`curves.points_num()`. Traversal is more effective as only selected
indices get visited. Also point data is copied by point ranges instead
of point by point.
Performance was tested with following code:
```cpp
TEST(curves_geometry, DuplicatePoints)
{
CurvesGeometry curves = create_basic_curves(100000, 100);
IndexMaskMemory memory;
IndexMask every_second = IndexMask::from_predicate(
curves.points_range(), GrainSize(100), memory, [](const int i) {
return bool(i % 2);
});
for (const int i : IndexRange(1000)) {
CurvesGeometry copy = curves;
const int expected_point_count = copy.points_num() + every_second.size();
ed::curves::duplicate_points(copy, every_second);
EXPECT_EQ(copy.points_num(), expected_point_count);
}
}
```

`BKE_main_ensure_invariants` was added in 1fae5fd8f6. The older
`ED_node_tree_propagate_change` was already implemented as a thin wrapper around
`BKE_main_ensure_invariants`. This patch removes the wrapper and calls the more
general function directly.
A new overload of `BKE_main_ensure_invariants` is added for the common case when
only a single data-block has been modified.

Main goals of this refactor:
* Make it more obvious which update function should be used.
* Make it more obvious which parameters are required by using references instead
of pointers.
* Support passing in multiple modified trees instead of just a single one.
No functional changes are expected.

The part that used the context does not seem to be necessary anymore. If the
given tree has any update tag set, the same notifiers will be sent anyway by the
`tree_changed_fn` callback.
If it turns out that we are now missing some notifier, then we have to change
the caller. It either has to call the proper `BKE_ntree_update_tag_*` function,
or create the notifier directly.
This change helps to generalize the concept of propagating changes in original
data, because the context is rarely available.

This caused build errors on the docs builder, I can't seem to reproduce
locally, so revert for now and have another look at some point in the
future.
Sadly as these changes usually go, this took 5c515e26bb and
2f0fc7fc9f with it as well.

Currently each node's position is stored in the coordinate space of
its parent. To find the location of a node on the canvas, we have to
apply the translation of each of its parents. Also, nodes have hidden
"offset" values used while transforming frame nodes. Together,
those made the system much more complicated than necessary,
and they made the Python API ineffective.
This commit removes usage of the offset values and moves nodes
to be stored in the "global" space of the node canvas. It also resolves
some weird behavior when resizing frame nodes, and fixes a few bugs.
The change is forward compatible, so we still write files with nodes in
the old parent-space format. In 5.0 the conversion when writing can be
removed. The existing Python API also stays the same. A new
"location_absolute" property gives node locations in global space,
and changing the old property also moves the child nodes of frames.
Resolves#92458, #72904.

Avoid rebuilding BVH trees when meshes are copied.
Similar to the other uses of the shared cache system,
this can arbitrarily improve performance when meshes
are copied but not deformed and BVH building is the
main bottleneck. In a simple test file I got a 6x speedup.
The amount of code is also reduced and the system is
much simpler overall-- built out of common threading
patterns like `SharedCache` with its double-checked lock.
RAII is used in a few places to simplify memory management
too.
The downside is storing more `SharedCache` items in the
mesh runtime struct. That has a slight cost when copying
a small mesh many times, but we have ideas to improve that
in the future anyway (#104327).

The order of curves in a Grease Pencil drawing defines the
order in wich they are rendered, so it's important to be
able to change the order. Currently, there is not easy way
to do this from python.
This adds a new `reorder_curves` and `reorder_strokes`
function to reorder the curves in the curves geometry.
The function takes in an array of indices that are the
new indices for the curves (e.g. an index map).
`reorder_curves(new_indices=[...])`

Restore overlay depth drawing which was removed in [0].
For viewport navigation this is useful. Disable overlays
for other operations such as painting & object placement.
Also disable color drawing in the overlay_next engine drawing
when drawing depth, since it caused the viewport to show a
checkered backdrop.
Details:
A boolean argument has been added to ED_view3d_depth_override instead
of new enums in eV3DDepthOverrideMode since mixing object-filtering
and draw-type in the one enum gets verbose & awkward, where most
existing enums would have needed to include NO_OVERLAY in their name.
V3D_DEPTH_NO_OVERLAYS has been renamed to V3D_DEPTH_ALL,
the caller must pass in use_overlay as false.

Add `bool MutableSpan<T>::contains(const T &value)` function, which is an
exact copy of the function from the `Span<T>` class. This makes it possible
to call `.contains()` directly on the `MutableSpan`, instead of having to
call `.as_span()` first.
Note that the `contains_ptr()` function was already copied from `Span` to
`MutableSpan` before.
No functional changes to the affected code, just the removal of the now
no longer necessary `.to_span()` call.

Removes redundant variables and duplicated logic. Some expressions
simplified. Refactored to make use of `OffsetIndices`. For example,
`Span<IndexRange> curve_interval_ranges` is rewritten into
`OffsetIndices<int> intervals_by_curve`.

Previously, some places used `curves.points_num() == 0` some other
places `curves.curves_num() == 0` to check if the geometry is empty.
Rather than having these two ways, add an `is_empty()` function
that replaces all these different checks.
Also update the curves geometry tests to use this function.

This implements the "Select Linked Pick" operator, by default exposed
in the keymap with `L` and `Shift-L`. This mirrors the existing operator
in legacy-curve edit mode and mesh edit mode.
The implementation is pretty simple, we just find the curve closest to
the mouse and change the selection of the points in that curve.

- Change variable names for consistency
- Split common code to function
- Create simple struct with curly brackets
- Avoid random access to IndexMask
- Remove obvious comments
- Use const references for float3
Handle the case separately when end points of strokes are selected.
Always deselect them (i.e. set "true", later array values are inverted)
when executing select less operation.

This improve the API in multiple aspects:
* No need for an additional `lookup` call to get the current attribute. This
would internally iterate over all attributes again. This leads to O(n^2)
behavior. Note that there are still other reasons for O(n^2) behavior when
processing attributes (where n is the number of attributes).
* Remove the need to return a value from the iteration code to indicate that the
iteration should continue. This is now the default behavior. The iteration can
still be stopped by calling `iter.stop()`.
* Easier access to `is_builtin` property.
* Iterator callback only has a single parameter instead of two (of which one is
sometimes unused).
