Document supported CLDR versions in the javadoc

Summary

Add a table describing JDK releases vs. CLDR versions.

Problem

CLDR locale data is updated in each JDK feature release, but users cannot easily distinguish which version of CLDR is included in a JDK feature release.

Solution

Add a table to the class description of java.util.spi.LocaleServiceProvider, mapping JDK feature releases to CLDR versions. This table will be non-normative because the use of CLDR locale data is an implementation characteristic of the JDK, not a mandate from the Java Platform Specification. In style, the table will look similar to the (normative) table in java.lang.Character that maps Java Platform releases to Unicode versions.

As with Unicode versions, JDK update releases do not backport newer CLDR versions, since it would break compatibility. One exception is the mapping of Windows zones to IANA's TZ data base, which will be backported (if any) as a part of the time zone update process.

Specification

Add the following @implNote to the end of the java.util.spi.LocaleServiceProvider class description:

+ * @implNote The JDK uses locale data from the Unicode Consortium's
+ * <a href="http://cldr.unicode.org/">Common Locale Data Repository (CLDR)</a>

+ * update releases in a given JDK release family use the same CLDR version.

As an editorial matter, it is desirable to clarify some terminology in the class description for java.util.spi.LocaleServiceProvider. This mainly means using the term "locale data provider" instead of "locale provider" (which could be confused with the "locale service provider" itself). The following changes are purely editorial:
