[klib] Don't pass around metadata serialization closure

Pass the metadata serializer instance instead. This allows to further
reduce code duplication by introducing the common interface
`KlibSingleFileMetadataSerializer` for abstracting away K1 and K2
representation of a source file, as well as reusing
`Fir2KlibMetadataSerializer` across different backends.
