Instead of two levels of focus with `focus` and `selected`, use a recursive
level. The components set the one "active" and hbox/vbox/dbox

Some users might destroy `this`, which would result in UAF.
In the future, we should consider alternatives like posting a task to
the main loop, or rely on users for this.

Dragging the mouse with the left button pressed now avoids activating multiple
checkboxes.
Add support for detecting mouse press transition. Added:
```cpp
// The previous mouse event.
Mouse Mouse::previous;
// Return whether the mouse transitionned from:
// released to pressed => IsPressed()
// pressed to pressed => IsHeld()
// pressed to released => IsReleased()
bool Mouse::IsPressed(Button button) const;
bool Mouse::IsHeld(Button button) const;
bool Mouse::IsReleased(Button button) const;
```
A couple of components are now activated when the mouse is pressed,
as opposed to released.

1. Stop taking Ref<XxxOption> in Component constructors. Instead, use
the XxxOption directly. Passing by copy avoid problems developers had
where one was shared in between multiple component, causing issues.
2. Add variants of most component constructors taking a struct only.
This replaces:

In the past, FTXUI switched from std::string to std::wstring to support
fullwidth characters. The reasons was that fullwidth characters can be
stored inside a single wchar_t.
Then FTXUI added support for combining characters. A single glygh
doesn't even fit a wchar_t. Instead, a glyph can be arbitrary large.
The usage of wstring doesn't really fit the new model and have several
drawbacks:
1. It doesn't simplify the implementation of FTXUI, because of combining
characters.
2. It reduces drawing performance by 2x.
3. It increase Screen's memory allocation by 2x.
This patch converts FTXUI to use std::string internally. It now exposes
std::string based API. The std::wstring API remains, but is now
deprecated.
Tests and examples haven't been update to show the breakage is limited.
They will be updated in a second set of patches.

From CppCoreGuidelines:
Rule of Zero: C.20: If you can avoid defining default operations, do.
C.52: Use inheriting constructors to import constructors into a derived class that does not need further explicit initialization.
DRY forward and using declarations.
Miscellaneous:
Fix format.sh to output examples with normalised paths in sorted order.
