Add Yetus InterfaceAudience annotations to Parquet

Parquet should use [Yetus InterfaceAudience annotations](https://yetus.apache.org/documentation/in-progress/audience-annotations-apidocs/org/apache/yetus/audience/package-summary.html) to specify its API's intended [audience](https://yetus.apache.org/documentation/in-progress/audience-annotations-apidocs/org/apache/yetus/audience/InterfaceAudience.html) (public/private) and optionally [stability](https://yetus.apache.org/documentation/in-progress/audience-annotations-apidocs/org/apache/yetus/audience/InterfaceStability.html) (unstable/evolving/stable) in code annotations both for the benefit of its users and also for ensuring that no breaking changes happen in the public API.

_{**Note**: *This issue was originally created as [PARQUET-1116](https://issues.apache.org/jira/browse/PARQUET-1116). Please see the [migration documentation](https://issues.apache.org/jira/browse/PARQUET-2502) for further details.*}

No source files or tests are named. Start by reviewing the Yetus InterfaceAudience and InterfaceStability documentation, then inventory Parquet's Java API to determine which classes and methods need annotations. Done means the intended audience and, where applicable, stability are documented in code across the API, with the stated protection against breaking public changes.
