MySQL 5.7 introduced `ALTER TABLE ... RENAME INDEX old TO new` (and the `RENAME KEY` synonym) as a metadata-only operation that renames an index without rebuilding it.

There was a problem hiding this comment.
Missed this before, given that we introduced this node should move this to generator.py, otherwise MySQL -> Other would error out with "Generator missing exp.RenameIndex.
We can also move the parsing to the base parser if we want to avoid overriding MySQL, up to you.
