cue/parser: allow full expressions for embeddings

This completes the implementation of the spec
allowing expressions for embeddings.

It also lifts the restriction in the spec.

Futher relaxing would be possible, but requires
lookahead.

Not that this is not unlike the Go ambiguity:
if foo == myStruct{} {
}
where parenthesis are required around the struct
literal.

Closes #106.
