Fix: Knife undo with no cut segments left

Now if a user presses the knife tool undo key when there are no more cut segments to undo, the operator exits. Previously, it did nothing.

Cleanup: Make format

Cleanup: Compositor: Migrate most input nodes to new socket builder

This migrates most nodes except for the image/render layer nodes.
These nodes require dynamic sockets so their implementation will be more involved.

Cleanup: use C comments for plain text

Cleanup: trailing space, newlines at EOF

Cleanup: sort cmake file lists

Cleanup: spelling in comments

Cleanup: Removed redundant if macro

Geometry Nodes: Fields version of attribute proximity node

Add a fields-aware implementation of the attribute proximity node.
The Source position is an implicit position field, but can be
connected with a position input node with alterations before use.
The target input and mode function the same as the original node.

Patch by Johnny Matthews with edits from Hans Goudey (@HooglyBoogly).

Compositor: Add support for canvas compositing

This commit adds functionality for operations that require pixel
translation or resizing on "Full Frame" mode, allowing to adjust
their canvas. It fixes most cropping issues in translate, scale,
rotate and transform nodes by adjusting their canvas to the result,
instead of the input canvas.

Operations output buffer is still always on (0,0) position for
easier image algorithm implementation, even when the
canvas is not.

Current limitations (will be addressed on bcon2):
- Displayed translation in Viewer node is limited to 6000px.
- When scaling up the canvas size is limited to the
scene resolution size x 1.5 . From that point it crops.

If none of these limitations are hit, the Viewer node displays
the full input with any translation.

Cleanup: Remove XRange and YRange in Compositor

Mostly unused and originally meant for areas with positive values.
With canvas compositing areas position may be negative.

Compositor: Full frame Glare node

Part of T88150.

Compositor: Replace resolution concept by canvas

This is a code refactor in preparation of supporting canvas
compositing. See {D12466}.

No functional changes, all canvases are at (0,0) position matching
tiled implementation.

Fix error in previous commit

`v_other` -> `v_step`

Fix flag wrongly set in 'BM_face_split_edgenet_connect_islands'

Sometimes the `use_partial_connect` option could trigger the assert:
```
BLI_assert(!BM_elem_flag_test(l_iter->v, VERT_NOT_IN_STACK));
```

This can happen when `v_delimit->e` is not part of edgenet, so `v_other` will not have the flag.

Cleanup: convert compositor nodes to c++

- Many cleanups of to use list base
- Some variable changes

These change is needed to migrate to the new socket builder API

Cleanup: Sort node types alphabetically

Geometry Nodes: Field version of curve reverse node

The updated version has a selection input as a field
and does not realize instances implicitly.

Fix potential render tests error with invalid utf-8 characters

In general should not happen, but better to report the actual error instead
of the Python test code failing.

Geometry Nodes: Remove experimental option for fields

This enables fields as the official workflow for geometry nodes.
While many features are converted to use fields rather than the old
attribute workflow, many are not yet converted. In that case, the
unconverted nodes are still accessible with an experimental option.
In the coming weeks the rest of the nodes will be converted.
