8358734: Remove JavaTimeSupplementary resource bundles

[naotoj]

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

Cleanup looks good to me.

[justin-curtis-lu]

For safety, should we have some type of failure if this is not true, similar to the previous CCE.

[naotoj]

I think this is acceptable. If, for some reason, adapter is not an instance, it will simply be ignored. That cast was a mere artifact from a time before we had this instanceof construct and we knew it wouldn't throw a CCE.

Thank you for the reviews!
