<i18n dev> RFR: 8154520: java.time: appendLocalizedOffset() should return the localized "GMT" string

[naoto.sato at oracle.com]

Hi Thejasvi,

Thanks for fixing this.

Since those new test cases depend on the CLDR localization, which might 
change in other implementations, those test cases should be in 
jdk/java/time/test directory, as "tck" tests should only test the spec. 
Please create a new test case for this in the "test" directory (with 
@modules jdk.localedata directive) similar to the existing TCK one. Also 
the current test in the TCK should enforce that it runs in Locale.US so 
that the result should match "GMT."

This change is to return the localized version of "GMT" instead. So for example, instead of returning "GMT +5.30", it may now return "XXXX +5.30" where "XXXX" is the localized string for "GMT" for the locale associated with the formatter. I have used DateTimeTextProvider.getLocalizedResource() method to return the "gmtZeroFormat" value from CLDR/LDML corresponding to the given locale. The code defaults to "GMT" in the absence of such a localized value.
