Allow option to use preventScroll in DayButton focus calls

[austin-reed-iseatz]

When opening the Datepicker at a large zoom level (200+), if any of the DayButton components get focused on, the screen will scroll to the focused DayButton. This can sometimes lead to situations where the input the opened the DatePicker is no longer visible and can lead to a loss of contextual information for the user as they may no longer be able to see things like the input label or helper text.

@austin-reed-iseatz this is an expected behavior in HTML and it is something we cannot address via DayPicker (which doesn't include any input, BTW).
