[Pipe] Use buffered input for TsFile scan parser

[Caideyipi]

Description

Use buffered input for Pipe TsFile scanning

• Upgrade TsFile to 2.3.2-260720-SNAPSHOT, which includes BufferedTsFileInput.
• Use BufferedTsFileInput for the no-modification path of TsFileInsertionEventScanParser, where the reader performs small sequential reads.
• Keep the existing metadata-loading and device-metadata-cache behavior when modifications are present.

Preserve old TsFile compatibility

The TsFileInput-based TsFileSequenceReader constructor does not initialize the compatibility deserializer. The parser therefore checks the file version before transferring ownership of the buffered input and falls back to the original String-based constructor for older TsFile versions.

Validation

• mvn spotless:check -pl iotdb-core/datanode
• mvn checkstyle:check -pl iotdb-core/datanode
• mvn dependency:tree -pl iotdb-core/datanode -Dincludes=org.apache.tsfile:* -Dverbose
• DataNode javac reached all main sources without errors in the changed file; the module remains blocked by unrelated stale generated/i18n/Thrift symbols in the local workspace.
