qdoc: Clear outputdir in -prepare phase only

qdoc now clears the outputdir in the -prepare
phase but not in the -generate phase. It also
does not print error and warning messages in
the -prepare phase. It does print fatal errors
in the -prepare phase, of course, and the QML
parser prints syntax errors in the -prepare
phase, but all the qdoc errors and warnings
are only printed in the -generate phase.

Task number: QTBUG-27688
