PY-14599 Make check that symbol is moved from/to importable module more picky

New policy is:
* Do not check name of the source file at all (if module was
unimportable before, moved symbol could not have references outside of
its file anyway).
* Do not check name of destination file if moved symbol had no
external references to it (outside of its own body), so that no imports
should be created/updated.
