Add format for narrow week days

[ghost]

It seems that the DateFormat class does not support narrow week days.

Reference:
intl/lib/src/data/dates/symbols/en_US.json

"NARROWWEEKDAYS":["S","M","T","W","T","F","S"],
"STANDALONENARROWWEEKDAYS":["S","M","T","W","T","F","S"]

It does seem like that. Rather odd. I don't want to make up formats, though. These are based on ICU, so it seems either we're not implementing one of theirs correctly or else we're missing a format specifier. (Or maybe they don't support it either).

Hmm, will intl add a format specifier for narrow week days in the future?

I think narrow week days are useful for calendar day titles. And I saw that Formatting Dates and Times - ICU User Guide has a field pattern for narrow week days(EEEEE). Maybe we can add a DateFormat.EEEEE([locale]) method that return narrow week days format. Of course, this is just my personal thought.

Field Patterns	Examples
E, EE, or EEE	Tue
EEEE	Tuesday
EEEEE	T
EEEEEE	Tu
