Get interval pattern for a given skeleton format.

The format string does contain pattern symbols (e.g. "yMMMd" or "Hms") and will be converted into the pattern in the used
locale, which matches the wanted symbols best. The symbols must be in canonical order, that is:
Era (G), Year (y/Y), Quarter (q/Q), Month (M/L), Week (w/W), Day-Of-Week (E/e/c), Day (d/D),
Hour (h/H/k/K/), Minute (m), Second (s), Timezone (z/Z/v/V/O/X/x)

See http://unicode.org/reports/tr35/tr35-dates.html#availableFormats_appendItems

@param {string} sSkeleton the wanted skeleton format for the datetime pattern
@param {object|string} vGreatestDiff is either a string which represents the symbol matching the greatest difference in the two dates to format or an object which contains key-value pairs.
The value is always true. The key is one of the date field symbol groups whose value are different between the two dates. The key can only be set with 'Year', 'Quarter', 'Month', 'Week',
'Day', 'DayPeriod', 'Hour', 'Minute', or 'Second'.
@param {sap.ui.core.CalendarType} [sCalendarType] the type of calendar. If it's not set, it falls back to the calendar type either set in configuration or calculated from locale.
@returns {string|string[]} the best matching interval pattern if interval difference is given otherwise an array with all possible interval patterns which match the given skeleton format
