Pass locked rowHeightPx through CalendarPager to CalendarMonthPage

Add rowHeightPx parameter to CalendarPager and pass it through to
CalendarMonthPage. Remove onRowHeightMeasured callback which is no
longer needed since CalendarMonthPage now receives row height
externally. Update CalendarMonthView to pass rowHeightPx to CalendarPager.
