Always compile all QML files into resources files, instead of generating
resource files when using Quick Compiler. Saves some ifdefs in the code,
since the file uris are the same in both cases. Also we are no longer
dependent on the runtime path from QLibraryInfo::Qml2ImportsPath. It had
problem in the prebuild QNX binaries, since the binaries had different
prefix than what was used in the device.
