<i18n dev> RFR: 8307547: Support for multiple collations for a locale [v3]

Thu May 11 18:35:50 UTC 2023

> The fix to https://bugs.openjdk.org/browse/JDK-8306927 switched the default collation for Swedish to the modern one. In order to provide a means for users who need the old collation, this PR intends to make `Collator` recognize the `co` Unicode locale extension so that multiple implementations for a locale can be provided. I would also like reviews for the corresponding CSR.
