Use CLDR locale provider on JDK 23+ (#110222)

JDK 23 removes the COMPAT locale provider, leaving CLDR as the only option. This commit configures Elasticsearch
to use the CLDR provider when on JDK 23, but still use the existing COMPAT provider when on JDK 22 and below.

This causes some differences in locale behaviour; this also adapts various tests to still work whether run on COMPAT or CLDR.
