Prior to this commit, Spring would create directly
`SimpleMetadataReaderFactory` instances or would manually create
`CachingMetadataReaderFactory` which extend
`SimpleMetadataReaderFactory`. This would prevent usage of the new
`ClassFileMetadataReaderFactory` in our internal codebase.
This commit replaces manual instantiations with calls to
`MetadataReaderFactory` factory methods and makes
`CachingMetadataReaderFactory` delegate to another factory created with
the same factory methods.
This allows internal usage of `ClassFileMetadataReaderFactory`
internally.
