Nico Hartmann 6c9f799207 [Torque] Add Kythe api to Torque compiler
Prepare the Torque compiler to generate Kythe artifacts to be consumed
by CodeSearch.

Drive-by changes.
* Extend SourcePosition by an offset in the input string, as this is
  required by the Kythe graph.
* Correctly set missing identifier positions in Declarations.
