[parquet-thrift] move on from java 8

[dossett]

Now that java 8 is no longer supported, we can use language features introduced in later versions and get ahead of other changes for subsequent upgrades. I'm trying this in one module as a test of automating this with codex.

Codex generated summary:

• Replaced deprecated reflection APIs with getDeclaredConstructor().newInstance() and unified exception handling, enabled by Java 9+ deprecations now acceptable with Java 11 baseline.
• Adopted List.of and List.copyOf for immutable collections, removing verbose Arrays.asList/manual wrappers and leveraging Java 9/10 collection factories.
• Simplified null-defaulting with Objects.requireNonNullElse and removed redundant null checks made unnecessary by Objects.requireNonNull, both available in Java 9+.
• Modernized small collection usages (e.g., ArrayDeque for queues, diamond operator cleanup), consistent with Java 11 APIs and performance best practices.
