Add "call with a note" resources

Note: UX resource for ic_call_note_while; UX needs to send me proper
version in all resolutions.

- Added new CallSubjectDialog class to display the call subject dialog.
- Moved getLookupKeyFromUri from Dialer into UriUtils.
- Note: Limit of 16 chars is in place until b/22806380 is resolved.
