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`

before this change, the example in the doxygen document for CatchEvent()
does not use the documented function. hence the example is not that
useful for developers interested in a typical usage of this function.
after this change, the example is improved to added the call to
CatchEvent(), which allows the application to the Loop() function at
user input.

- Provide better defaults for ComponentBase `Focusable()` and
`ActiveChild()` methods. This resolves:
https://github.com/ArthurSonzogni/FTXUI/issues/335
- Implement `Container::Tab` 's `Focusable()` methods. This prevents
the users to navigate into a tab with no interactivity.
- Add support for SIGTSTP:
https://github.com/ArthurSonzogni/FTXUI/issues/330
This
- Add support for task posting.
This allows folks to defer function execution, and execute it directly
below the main loop. The task are executed in a FIFO order.
Use std::string by default for the implementation of FTXUI's input
component.
Along the way:
- Give a correct implementation for fullwidth characters.
- Add tests
- Modify the way the cursor is drawn.
This implement the flexbox elements, following the HTML one.
Built from them, there is also the following elements:
- `paragraph`
- `paragraphAlignLeft`
- `paragraphAlignRight`
- `paragraphAlignCenter`
- `paragraphAlignJustify`
This is a breaking change.
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.

- Password is now taking a ref, allowing a shared state to be used by
multiple passwords.
- Password cursor position is now optional. It will be used only when
set to something different from -1.
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.

- Invoke DetachAllChildren from ~ComponentBase
- Define Focused using Active
- Compact TakeFocus loop code
- const-correctness for Parent, Active and Focused
* Reorganize ContainerBase
- Reduce Container overloads using default arguments
- Extract member function pointers to virtual functions
- Separate classes for Vertical, Horizontal and Tab containers
* Collect unpack from NodeDecorator subclasses
* Reduce redundant expansion for aliases
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.
