The amount of triangles drawn by the button depends on its `sizex`.
See:
```
immBegin(GPU_PRIM_TRI_STRIP, (sizex + 1) * 2);
```
Therefore the `sizex` cannot be 0.
Solution a bit similar to rB56b0cd1d.

Applying/undoing incremental changes didn't fit well when
mixed with periodic snapshots from mem-file undo.
This moves to a much simpler undo system.
- Uses array storage with de-duplication from `BLI_array_store`.
- Loads the buffer into existing text data,
for better performance on large files.
- Has the advantage that Python operators can be supported
since we don't depend on hard coded undo operations.
Solves T67045, T66695, T65909.
We need to indicate a preferred size to avoid `RGN_FLAG_TOO_SMALL` the first time the region is created.

Changing the brush size for example,
was adding redundant undo steps in paint-modes.
For now, don't store undo steps for property changes
in paint & edit modes.
While not ideal, this is similar to 2.7x behavior.
- Add 'Navigation Buttons' preference, used for 2D views
(previously this couldn't be disabled).
- Add "Off" option for 3D view axis.
- Support minimal axis with navigation buttons.
When button text doesn't already show the label,
include the label in the tool-tip.
Without this the descriptions for icon-only buttons
don't always make sense.
This also gives a tool-tip for icon-only popovers.

Better to make internal code naming match official/UI naming to some
extent, this will reduce confusion in the future.
This is 'breaking' scripts and files that would use that feature, but
since it is not yet officially supported nor exposed in 2.80, as far
as that release is concerned, it is effectively
a 'no functional changes' commit.
Cheap tip: anything that is not "Camel Case" and/or that is more than
a few words long should use `TIP_` translation, not `IFACE_` one.
Also added several missing strings (including the one reported in D5056
by Jean First (@robbott), thanks).
Modulo makes no sense here at all, is from an old bugfix to prevent a crash
that is no longer an issue.

Each constraint now has a unique icon, just like modifiers.
Icons are designed by Andrzej Ambroż & Alessio Monti, with user input.
