cue: disallow bulk optional fields with other fields
This change is the first step to change the semantics
of bulk optional fields to apply only to additional fields.
The first step is to encourage bulk optional fields to be
in a struct with any other field.
`cue fmt` now rewrites violating bulk optional fields by
wrapping them in a embedded struct, which is
equivalent.
TestDiff was changed to ensure that diff will identify
the two forms as equivalent.
