feat: improve keyboard handling and events

[arthurdenner]

Acessibility and events fixes and features.
What kind of change does this PR introduce?

What is the current behavior?

1. When navigating with the keyboard, if a button is selected, its action is performed but focus is lost;
2. We can't navigate with arrow keys between the dates;
3. onBlur is fired in weird situations;
4. onFocus is not supported;
5. Clear button is not accessible by keyboard.

What is the new behavior?

1. After the rerender caused by a button's action, if the button is still available on the screen, it's gets focused again;
2. It's possible to navigate with arrow keys between the dates;
3. onBlur is only fired when the user actually leaves the input;
4. onFocus is fired every time the input is focused;
5. Clear button is accessible and responds to keyboard events.
