8390388: Cherry-pick tz attributes from newer CLDR data for jdk25u and earlier

[jerboaa]

Using Backport <bug> because the bug exists, but no public sha to compare it to. This patch implements the described changes in the bug. In particular takes:

1. metaZones.xml changes from Update CLDR to Version 48.2 JDK-8371842 as well as changes to TestZoneTextPrinterParser.java so as to avoid the test failure for America/Vancouver when run. See first and third commit.
2. Pick dstOffset and stdOffset changes from Update CLDR to Version 48.0 JDK-8354548 in ldmlSupplemental.dtd. Added relevant hunks from ldmlSupplemental.xsd to keep them aligned. See second commit.

Testing:

• test/jdk/sun/util/resources, test/jdk/java/time/test and test/jdk/java/util/TimeZone on Linux x86_64. All pass:

I would add the other dstOffset metazone additions from CLDR 48 so the attribute is used consistently with later JDKs:

$ git show 2c3c4707c0ac|grep dstOffset
+<!ATTLIST usesMetazone dstOffset CDATA #IMPLIED >
+      <xs:attribute name="dstOffset"/>
+				<usesMetazone to="2017-10-23 22:00" from="1994-03-20 22:00" mzone="Africa_Western" stdOffset="+01" dstOffset="+02"/>
+				<usesMetazone mzone="Irish" to="1971-10-31 02:00" stdOffset="+00" dstOffset="+01"/>
+				<usesMetazone mzone="GMT" from="1971-10-31 02:00" stdOffset="+00" dstOffset="+01"/>

I also don't see the need for bringing in the blank lines above plurals. It's not like this will make the files match as there are other schema changes we don't want to bring in.

The 48.2 changes look fine. Do you know why three of the tests were skipped?

Do you know why three of the tests were skipped?

Jtreg printed did not match keywords: 1; did not meet platform requirements: 2. And indeed DefaultTimeZoneTest.java is a manual test for windows (the keword mismatched test), Bug8066652Run.java is a test for mac only and AIXTzMappingTest.java is for AIX only.

OK. Done in 71ebe9f and 1c34477 (whitespace). More thoughts?

Change look ok. I'll do a final review once #757 is in and this is rebased on master.
