[Feature Request] Navigate calendar days with keyboard

[dogancelik]

Is your feature request related to a problem?

Changing date is not possible with with keyboard.

Describe the solution you'd like

The days on the calendar should be focusable and navigatable by keyboard keys (up, down, left, right).

I should be able to Tab to Close button and press Enter to close Calendar dialog.

Describe alternatives you've considered

Solution 2: Make calendar dialog optional, make input editable

So you can input text as usual like 18/07/2020

Input format is detected by user's locale, I use YYYY.MM.DD, set in Windows locale settings.

Additional context

I provided example designs above.

This is more related to #7954 but I understand if maintainers want to combine issues into one single issue.
