<i18n dev> RFR: 8377013: TimeZone.getDefault() returns obsolete id on Windows (Asia/Calcutta) [v2]

[Naoto Sato]

> Fixing the Windows default time zones returned from `TimeZone.getDefault()` for some regions. On Windows, it uses their own regions for time zones that aren't 1-1 match to IANA's TZ database. Thus a mapping table is created as `conf/tzmappings` on Windows Java runtime. It is derived from CLDR's `windowsZones.xml` but it uses the obsolete IANA ids for their compatibility reasons. The fix is to replace the CLDR's old ids to the latest IANA ids for those regions.
> Since it is hard to provide an automated test, as it involves the modification of the Windows' default time zone, regression test is not provided. Instead the fix is manually confirmed using the JIRA issue's example. Since this is a change in behavior, I will file a corresponding CSR/RN.
