[Platform] Implement functions for localized time format information

• Component: Platform
• Status: RESOLVED FIXED

For implementing "time" input type, we would like to have following functions:
* localizedTimeFormatText() returns time format with second, e.g. "h:mm:ss a"
* localizedShortTimeFormatText() returns time format without second, e.g. "h:mm a"
* periosLabels() returns localized strings of AM/PM.

Why do you need both of non-short and short formats?

> +          2. periodLabels()

The name periodLabels() is too short and not concrete.
How about timeAMPMabels(), or separate it into timeAMLabel() and timePMLabel()?

= Changes since last review =
* Replace INPUT_TIME_FIELDS => INPUT_TYPE_TIME_MULTIPLE_FIELDS
* Replace periodLabels => timeAMPMLabels
** Thanks for suggestion. This is more explicit.
** For consistency of month names and weekday names, returning vector seems to be better.
* Having TimeFormat and ShortTimeFormat for displaying only two fields hour and minute when step >= 60. There is no way to remove second field from "h:m:s" pattern string. We don't know whether ":" after "m" belongs minute or second field.

WebCore::localized*TimeFormatText() ask LDML format strings, but they are ICU format strings.  Probably you have an assumption that ICU returns LDML-compatible formt strings. We need a comment.
