Don't update extra compilers individually after project load

Browse Source 
Each call of CppModelManager::updateSourceFiles detaches the current
snapshot.
The extra compilers where set up and triggered individually, and
resulted in individual updateSourceFiles calls with the single result
file of the extra compiler. For Qt Creator this would lead to 200
calls in quick succession after project load, potentially leading to a
freeze of multiple seconds.

Instead of updating the result files of the extra compilers individually
after project load, integrate the update into the regular project source
file update. So we end up with only a single call of updateSourceFiles.
For this the project updater needs to trigger the extra compilers, and
wait for all to finish as well as the regular project part update,
before
triggering the parser.
