Java: Tag quality queries with quality and sub-category

[owen-mc]

Updated tags for high and very high precision quality queries, using the query metadata guide. It is intended that all of these queries will now be in the quality suite.

I used copilot to do most of these, though I did review them all and change many of them.

Something that came up several times is a query that finds what is probably a coding mistake which leads to dead code. I erred on the side of tagging these as correctness (or sometimes error-handling) rather than useless-code, as the more serious issue is that the code probably contains a correctness error, rather than that there is some useless code that should be deleted.

The existing efficiency and logic tags seem to be superseded by the new performance and correctness sub-categories, but I will leave removing them for another PR so as not to delay this one.

Pull Request Overview

This PR adds the new quality top-level tag and appropriate sub-category tags (e.g., reliability, correctness, performance, etc.) to Java CodeQL queries, replacing legacy maintainability, reliability, and efficiency tags for consistency. It also updates the change notes to document these metadata changes. Removal of all legacy tags is deferred to a future PR.
