qqmljsscope: add ownModuleName

Allow qqmljsscopes of QML components to have "own" module names, and
add a helper method moduleName() that helps retrieve the module name
of some (possibly non QML component) qqmljsscope by iterating over its
parents.

That is required for the renaming of qmlcomponents and allows to check
if the qml element to be renamed is defined in the same module as the
current module. (It is not allowed to rename a QML component from
another module).
