Reviewed by Kentaro Hara.

Source/WebCore:

This is a preparation to remove LocalizedData.h.

Add the following pure virtual member functions to Localizer.
  parseDateTime
  formatDateTime
  dateFormatText.

We rename existing parse/format functions for type=date in Locale*
classes, and extend their functionality so that they support other
date/time types. They override the new functions of Localizer.

No new tests. This should not change any behavior.

* platform/text/Localizer.h:
(Localizer): Add parseDateTime, formatDateTime, and dateFormatText.

* platform/text/LocaleICU.h:
(LocaleICU):
- Rename parseLocalizedDate to parseDateTime
- Add type argument to parseDateTime
- Rename formatLocalizedDate to formatDateTime
- Rename localizedDateFormatText to dateFormatText
- Make parseDateTime/formatDateTime/dateFormatText virtual.
* platform/text/LocaleICU.cpp:
(WebCore::LocaleICU::parseDateTime):
Renamed. Reject non-date types.
(WebCore::LocaleICU::formatDateTime): ditto.
(WebCore::LocaleICU::dateFormatText): Renamed.
* platform/text/LocalizedDateICU.cpp: Moved some code to LocaleICU.cpp.
(WebCore::parseLocalizedDate):
(WebCore::formatLocalizedDate):

* platform/text/LocaleNone.cpp:
Add empty implementations of parseDateTime, formatDateTime, and
dateFormatText.
(LocaleNone):
(WebCore::LocaleNone::parseDateTime):
(WebCore::LocaleNone::formatDateTime):
(WebCore::LocaleNone::dateFormatText):

* platform/text/LocaleWin.h:
(LocaleWin):
- Rename parseDate to parseDateTime
- Add type argument to parseDateTime
- Rename formatDate to formatDateTime
- Make parseDateTime/formatDateTime/dateFormatText virtual.
* platform/text/LocaleWin.cpp:
(WebCore::LocaleWin::parseDateTime):
Renamed. Reject non-date types.
(WebCore::LocaleWin::formatDateTime): ditto.
* platform/text/LocalizedDateWin.cpp: Moved some code to LocaleWin.cpp.
