Fix indent of MLDataFormats.proto (apache#9181)

Currently, our protobuf definition files have a mixed indent of tabs and spaces, which will make them have a different visual effect on different editors or IDEs, and it may become noise in code review.

Unfortunately, we don't have an automatic way to keep protobuf files in good format yet. This PR replaced existing tabs in protobuf definition files with spaces.
