source-mysql: Always include charset in new metadata

It was always the plan to include the table charset in the table
metadata unconditionally, I just left that part for a followup
commit to keep the diffs separate.

This removes the `"utf8mb4" -> ""` omission from the replication
code so that it's always made explicit what charset a table is
using in metadata initialized after this change. The default of
`"" -> "utf8mb4"` still exists in the DDL alteration datatype
translation so that will always be explicit for newly added
columns, and likewise the string decoding function defaults
`"" -> "utf8mb4"` so that old metadata works, but after this
change we always specify charset information explicitly when
generating new metadata.
