Move HIDE_VOICEMAIL_SETTINGS_MENU out of voicemail/impl

The metadata belongs with the voicemail settings menu, which is moved into dialer a while ago. Not moving the metadata causes build variants without VVM to have duplicated voicemail settings in telephony and dialer.

Also removed the redundant metadata in incall ui manifest.
