[FIX] sap.m.ObjectIdentifier: now utilizes Text and Link controls

The title and text sections of the control are now rendered using Text
and Link controls. This solves the following issues:
- No outline when the title has focus;
- Focus does not fall back to the title if e.g. a dialog was opened by
pressing the title;
Adapted the qUnit tests according to the new rendering. Implemented
visual spec for ObjectIdentifier inside a table.
