[filesystem] Isolate Jindo OSS presigning dependencies (#9856)

[jerry-024]

Summary

Backport #9856 to release-2.1 to isolate Jindo OSS presigning dependencies from the embedding application's classpath.

Changes

• Load OSS presigning classes and runtime dependencies from a private Jindo plugin directory through the existing PluginLoader mechanism.
• Preserve Jindo packaging metadata, notices, and JDOM/JAXB license resources.
• Add coverage for plugin isolation, minimal and conflicting host classpaths, multi-release entries, and presigner class boundaries.

Testing

• mvn -B -ntp -pl paimon-filesystems/paimon-jindo -am -DskipTests -Dmaven.jar.forceCreation=true clean install
• mvn -B -ntp -pl paimon-filesystems/paimon-jindo '-Dtest=JindoFileIOTest#testCreateBlob*+testDisable*+testKeep*' -DwildcardSuites=none test (4 tests)
• mvn -B -ntp -pl paimon-filesystems/paimon-jindo surefire:test@integration-tests (23 tests)
• git diff --check

Notes

• Cherry-picks merge commit de872c4df69f2c03394e2758c3c55659e8f5888c without conflicts or additional changes; the patch ID matches upstream.
• Local verification used JDK 11 on macOS arm64 and does not include a live Doris/OSS deployment.
• Replaces the equivalent closed backport [filesystem] Isolate Jindo OSS presigning dependencies (#9856) #9880.
