[HUDI-5151] Fix bug with broken flink data skipping caused by ClassNotFoundException of InLineFileSystem

[trushev]

Change Logs

Pls follow the ticket for more details

This problem has already been fixed by #5194. But the patch doesn't fix flink's issue

We should use InLineFileSystem.class.getClassLoader() instead of Thread.currentThread().getContextClassLoader() because method lookupRecords(keys, fullKey) is called from commonForkJoinPool-worker thread which may contain the wrong contextClassLoader

Impact

Fixed flink data skipping issue
