[PR] [core] Coalesce concurrent CachingCatalog table loads [paimon]
officialasishkumar opened a new pull request, #7840:
URL: https://github.com/apache/paimon/pull/7840
### Purpose
Fixes #7484.
`CachingCatalog#getTable` now uses Caffeine's atomic cache loading path for regular tables, so concurrent cache misses for the same identifier share one `wrapped.getTable` call. System tables continue to wrap the cached origin table instead of being cached directly.
### Tests
- `mvn -pl paimon-core -Pfast-build -Dtest=CachingCatalogTest#testConcurrentGetTableLoadsTableOnce test`
- `mvn -pl paimon-core -Pfast-build -Dtest=CachingCatalogTest test`
- `mvn -pl paimon-core spotless:check`
