<i18n dev> RFR: 8358734: Remove JavaTimeSupplementary resource bundles

[Naoto Sato]

The parallel loading of JavaTimeSupplementary was a historical artifact from the introduction of JSR 310, which additionally loads resouces that had not existed before. Since the COMPAT locale provider which relied on this mechanism has been removed, and the CLDR resource bundles now include those resources by default, removing the parallel loading mechanism simplifies the implementation
