ticket:11674: Make ULocale work better with Android.

Android supports scripts and Unicode extensions, but not locale
categories. Instead of identifying Java version to determine
capabilities, this change introduces two booleans in JDKLocaleHelper,
one that tells whether the implementation supports locale categories,
and another that tells whether scripts and extensions are supported.

This looks mostly good to me, except: It would be much cleaner to break the one
try-catch block into two; the first one ending with
"hasScriptsAndUnicodeExtensions = true;" and the second one ending with
"hasLocaleCategories = true;" -- so that these two flags are tested truly
separately.
