 Update vector handling in similarity methods (#11013)

Distinguish between vectors that are 0 vs. missing vectors when warning
about missing vectors.

Update `Doc.has_vector` to match `Span.has_vector` and
`Token.has_vector` for cases where the vocab has vectors but none of the
tokens in the container have vectors.
