Split Resource Generation into two Action

Currently, there exists only one action that generates a .qmlrc file which is actually a .rcc file

auto action = new QAction(QCoreApplication::translate("QmlDesigner::GenerateResource", "Generate Resource File"));

This action should be split into two actions.

ne action would be called* "Generate QRC Resource File"* and 'should just' generate the .qrc file.
The second action called
"Generate RCC Resource File" should generate the .rcc file like the current action.

When generating the .rcc file the file dialog should give the opinion of .qmlrc or .rcc with .qmlrc as the default.
