UI: Draw real node sockets for node-input buttons and left-align them

Couple of reasons for this:
* Makes it easier to understand that and how these buttons map to nodes.
* These buttons represent node inputs, so it makes more sense to have the icons
on the left.
* We'd like to show the usual decorators on the right, but having two circles
for different purposes next to each other would be confusing.

Also respects the socket shape. So if a diamond shape is used for example, the
properties show that too.

I'm not sure if the previous icon textures were cached, either way this method
doesn't use the caching. So this adds a draw call for every socket icon which
is a bit annoying, but probably neglectable. Would be better if we'd use proper
icon textures or batches, but that's a separate change.

Fix T75032: New complex solidify algorithm handles poorly merging threshold of small geometry details.

* Implemented the algortihm that would merge vertices to the weighted
center between them.
* Exposed the merge threshold to the user.

The new default tolerance is 0.0001 (versionning code ensures that
previous default value remains in use to avoid any change in existing
files).

Fix T75677: Annotation in compositor/shading tabs loose AA after drawing stroke

The drawing of annotations in 2D was using a very old code created in 2.6x versions. Now it's using a standard shader as it's done while drawing.

Use column header for Armature Viewport Display panel.

GPencil: Add turnpolicy parameter to trace

This determines how turn in the trace process. (It uses Potracle lib values)

Fix T75667: Use of incorrect terminology in the brush_colors_flip operator

- The word 'Flip' is incorrect. 'Swap' or 'Switch' is correct.
- In Blender, we use 'primary' & 'secondary' color swatches, not 'foreground' and 'background'

Fix error in previous commit

I unintentionally changed the size of checkboxes, should be back to the
old size now.

Fix T75592: Correctly calculate length of curve verts

Previous commit to fix T75405 needed a small change to increase the
length of the front section of the curve when only the front is built.

Change padding around checkboxes

Two changes:
* Reduce padding between checkbox and text. That makes it clearer what
the checkbox belongs to if there's also a column heading in front of
the checkbox.
* Don't add padding on the left side of checkboxes. That makes them line
up better with items above and below it.

VSE: Add sample tool

This tool is set as default tool, so default action on click doesn't have pernament effect.
