Previously, SpaceAnalyzer set focus on the selected BreadcrumbButton.
Using arrow keys triggered the keydown_event of the AbstractButton,
which later on caused a Function object to be deleted while it is still
being used.
This change sets the focus on TreeMapWidget and adds an event handler
to TreeMapWidget for keydown events.
Fixes#13254.
With #12480, Breadcrumbbar's on_focus_change() uses
on_click(). In SpaceAnalyzer, double clicking triggers the
TreeWidgetMap's on_path_change(), which triggers Breadcrumbbar's
on_focus_change(), which also triggers the TreeWidgetMap's
on_path_change() again. This resulted in use-after-free of
Breadcrumbbar, thus resulted in the crash. Not updating the
TreeWidgetMap's viewpoint recursively solves the issue.
Function-local `static constexpr` variables can be `constexpr`. This
can reduce memory consumption, binary size, and offer additional
compiler optimizations.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.
This also moves Widget::load_from_json into Core::Object as a virtual
function in order to allow loading non-widget objects in GML (e.g.
BoxLayout).

This changes client methods so that they return the IPC response's
return value directly - instead of the response struct - for IPC
methods which only have a single return value.
This commit unifies methods and method/param names between the above
classes, as well as adds [[nodiscard]] and ALWAYS_INLINE where
appropriate. It also renamed the various move_by methods to
translate_by, as that more closely matches the transformation
terminology.

For small rects there was a disagreement between two parts of the
layout algorithm. There is a function that decides if there is
enough space in a rectangle for a label. But this function was
called on two slightly different rectangles.
