- 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.
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.
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
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.

When switching from raw pointers toward shared_ptr, the destructor
wasn't updated correctly.
This patch:
- Fixes the issue.
- Add two regression tests.
- Use address sanitizer for the tests.
This fixes: https://github.com/ArthurSonzogni/FTXUI/issues/115
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.
