Allow cascade _target to work with non toml fm
The TOML lib unmarshals slices of string maps to []map[string]interface{}
whereas YAML and JSON decode to []interface{}
The existing tests only check for TOML working correctly, and _target
with cascade did not work at all for frontmatter defined in other formats.
Add a function to normalize those slices
Fixes #7874
