[build] Migrate to Gradle version catalogs (#8524)

Also fixes the google compile-testing library to 0.23.0 (the latest
available at time of writing) instead of a wildcard

Jackson versions were inconsistent across projects; most were on 2.19.2,
but the fields subproject was on 2.15.2. All projects are now on 2.19.2
for consistency
