Problem Summary: Paimon JDBC system tables that execute through the BE JNI
scanner could not initialize the PostgreSQL JDBC driver, so queries such as
snapshots/manifests/partitions failed with `No suitable driver found`. This
change propagates JDBC driver metadata to BE and registers the driver in a
DriverManager-visible classloader before Paimon table initialization. The
regression case is also extended to cover all supported Paimon JDBC system
tables, including `row_tracking` on a row-tracking-enabled table.
### Release note
Fix Paimon JDBC catalog system table queries that run through the BE JNI
scanner.
### Check List (For Author)
- Test
- [x] Unit Test
- [x] Manual test (add detailed scripts or steps below)
- [ ] Regression test
- [ ] No need to test or manual test. Explain why:
- [ ] This is a refactor/code format and no logic has been changed.
- [ ] Previous test can cover this change.
- [ ] No code files have been changed.
- [ ] Other reason
Manual test:
- `./run-fe-ut.sh --run
org.apache.doris.datasource.property.metastore.PaimonJdbcMetaStorePropertiesTest,org.apache.doris.datasource.paimon.source.PaimonScanNodeTest`
- `env JAVA_HOME=/mnt/disk1/chenjunwei/doris_tools/jdk-17.0.9+9
/mnt/disk1/chenjunwei/doris_tools/apache-maven-3.9.9/bin/mvn -pl
be-java-extensions/paimon-scanner -am test -Dtest=PaimonJdbcDriverUtilsTest
-DfailIfNoTests=false`
- Verified all Paimon JDBC system tables on the local FE/BE cluster,
including `row_tracking` on a row-tracking-enabled table
- Behavior changed:
- [x] Yes. Paimon JDBC system tables now work through BE JNI scans.
- Does this need documentation?
- [x] No.
