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
