fix: https://github.com/ArthurSonzogni/FTXUI/issues/296#issue-1092343846
When the list in Radiobox/Menu/Toggle is resized, clamp the |selected_| values so that it stays within bounds.
Clamping is executed in Render() and in OnEvent()

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.

The target_compile_features command allows setting PUBLIC compile features for the library, making it implicit for the applications linking it. This reduces the CMake boilerplate required to set up a dependent project (eg. ftxui-starter).
