Issue #10755
Backporting the fix to 22.06
Fixes an issue in protobuf writer where the length on the row index entry was being written into a single byte. This would cause errors when the size is larger than 127.
The issue was uncovered when row group statistics were added. String statistics contain copies to min/max strings, so the size is unbounded.
This PR changes the protobuf writer to write the entry size as a generic uint, allowing larger entries.
