[JSC] Use `UFormattedValue` API in `IntlRelativeTimeFormat::formatToParts`
https://bugs.webkit.org/show_bug.cgi?id=307623
Reviewed by Yusuke Suzuki.
Use ureldatefmt_formatNumericToResult / ureldatefmt_formatToResult to
obtain both the formatted string and field position metadata in a single
ICU call.
Read UFIELD_CATEGORY_NUMBER fields directly from the UFormattedValue to
build number sub-parts, eliminating the separate unum_formatDoubleForFields
call and String::find lookup.
Pre-allocate UFormattedRelativeDateTime and UConstrainedFieldPosition
during initialization and reuse them across calls.
Extend IntlFieldIterator to support construction from a Vector of
pre-collected fields, so number fields from UFormattedValue can be
passed to IntlNumberFormat::formatToPartsInternal.
