CMake: Handle translations

(Optionally) re-generate .ts files from CMake by running lupdate and
run lrelease to generate .qm files.

Changes to qmake:

* src/libs/3rdparty/syntax-highlighting/src/cli/kate-syntax-highlighter.cpp
  is no longer translated: It's a command line tool that is not used by creator
* src/libs/aggregation/examples/text/main.cpp is no longer included in ts files
* src/libs/qt-breakpad/qtcrashhandler/* is no longer included in ts files:
  It is not built right now
