VNDK APEX doesn't use "apex_name" property

VNDK APEX has been using "apex_name" property to set "name" field in
apex_manifest. But setting apex_name had a side-effect of emitting
duplicate rules for symbol files for VNDK APEX and its override_apex.
(Please see the removed comments for more details about error)

Not using "apex_name" fixes the duplicate errors.

There're a few more vendor apexes with the same issue, which I will
handle in follow-ups.
