Into ftxui/component/, add:
```
Container::Stacked(...)
Window(...);
```
Together, they can be used to display draggable/resizable windows.

* Fix typo.
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:
https://github.com/ArthurSonzogni/FTXUI/pull/670
This fixes:
https://github.com/ArthurSonzogni/FTXUI/issues/426
Add the `SliderOption` option supporting:
```cpp
{
Ref<T> value;
ConstRef<T> min = T(0);
ConstRef<T> max = T(100);
ConstRef<T> increment = (max() - min()) / 20;
GaugeDirection direction = GaugeDirection::Right;
Color color_active = Color::White;
Color color_inactive = Color::GrayDark;
};
```
In particular, this supports multiple direction. This resolves:

This one do not support adding a label. The old constructors can still
be used to have a label.
Add decorator variants for decorator components
Add the "pipe" operator for components, similar to what was done for Elements.
We are able to put something like:
```
Button(...) | Maybe(&show_button)
```
Add decorators for:
- `Maybe`
- `CatchEvent`
- `Renderer`

ftxui::Ref<> is used for passing Options, for instance, MenuOption,
to the corresponding component which is supposed to hold a strong
reference of it. and we can observe the events sent to the component
by setting callback(s) in the option instance passed to the owner
component.
but the callback function is not always copyable, despite that it
might be moveable.
in this change,
* Make<>() is updated to use the perfect forwarding to avoid
enforcing its parameters to be copyable.
* Ref<> is also updated to take a rvalue reference, so we can
move away from the contructor parameter when creating an
instance of Ref<>() from it.

Dom
- `vscroll_indicator`. Show a scrollback indicator on the right.
Component
- `Maybe`: Display an component conditionnally based on a boolean.
- `Dropdown`: A dropdown select list.

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.

Allow Container::Vertical and Container::Horizontal to have an
external selector, similar to Container::Tab.
This is useful for implementing a menu of menu.

This allows developers to set child children component must be the
currently active/focused one.
This can be used to "control" where the focus is, without user
interactions.
