   …tially written proto files
   
   ### What changes were proposed in this pull request?
   This PR introduces a more lenient version of ProtobufInputFormat that 
ignores EOFException when reading partially written proto files.
   ProtobufMessageInputFormat skips zero-byte files by creating 
<SafeRecordReader>, which ignores EOFException. 
   
   
   ### Why are the changes needed?
   Abrupt AM termination or OOM failures can result in partially written 
protobuf files. When reading data from the corresponding external table, these 
incomplete files may trigger an EOFException, causing the entire query to fail.
   
   To improve resilience, it would be better to gracefully skip unreadable or 
corrupted proto files and continue reading the remaining valid data, instead of 
failing the entire query.
   
   
   ### Does this PR introduce _any_ user-facing change?
   Yes, this would silently skip reading partially written proto files instead 
of failing with EOFException.
   
   ### How was this patch tested?
   Manually tested with a sample partially written dag data file.
