QtQml: Reduce import and plugin paths for to plugin applicationsHEADdev

Plugin applications should generally not use environment variables since
those are meant for the host application. Furthermore, they should not
look at QCoreApplication::applicationDirPath() since that is the host
application's path. They can use the resource file system and their own
Qt installation's paths, though.

[ChangeLog][QtQml][Important Behavior Changes] The default import and
plugin paths for QML have been changed for applications that set the
Qt::AA_PluginApplication attribute. This attribute is meant to isolate
the plugin application from the host application. To achieve this goal,
it can't share plugin and import paths with the host application.
