Merge 129094 - REGRESSION(r127727): Calendar picker focus ring should be hidden until key event
https://bugs.webkit.org/show_bug.cgi?id=97165

Reviewed by Kent Tamura.

The regression was caused because NoFocusRing class was being removed
from then main element inside resetMain().

No new tests. Covered by calendar-picker-appearance.html.

* Resources/pagepopups/calendarPicker.js:
(initialize):
(CalendarPicker):
(CalendarPicker.prototype._layout):
(DaysTable.prototype._handleKey):
(CalendarPicker.prototype._handleBodyKeyDown):
(CalendarPicker.prototype.maybeUpdateFocusStyle): Make this a method of CalendarPicker because we don't use it for other pickers.
