Add better Japanese locale support for Calendar

[MayaKirova]

Currently there's limited Japanese locale support for the Calendar: https://www.infragistics.com/products/ignite-ui-web-components/web-components/components/scheduling/calendar#localization-and-formatting

However there are a few more language specific details that are not covered.

Expected:

It should show a calendar UI with naturally Japanese-formatted date strings.

Actual: It showed a calendar UI with incomplete Japanese-formatted date strings. This appearance is difficult to accept for Japanese people.

Details:

• In Japanese display text, a weekday should be enclosed in parentheses when the display text includes the month and day with the unit text "月" and "日".
• In Japanese display text, the line of weekday, month, and day must be ordered as month, day, and weekday. And, don't separate it with comma.
• In Japanese display text, the line of month and year must be ordered as a year before month.
• In Japanese display text, the unit of a year, "年", is required when the month in the same line has the unit, "月".
