<i18n dev> RFR: 8358095: Cleanup tests with explicit locale provider set to only CLDR [v3]

[Justin Lu]

> Please review this PR which cleans up some i18n tests.
> 
> There are some i18n related tests that set the locale provider to CLDR (and only CLDR). Since JDK9, this is redundant and equivalent to the default. Thus, occurrences of "-Djava.locale.providers=CLDR" are just extra noise for these tests. 
> 
> As this change is trivial cleanup, bug IDs are not updated in this change.
