Do not resolve URLs when assigning them to a property

We don't know in advance if a URL is part of the source code and should
be relative to the current element, or if it is part of the application
data and should not be touched.

[ChangeLog][QtQml][Important Behavior Changes] URLs are not resolved or
intercepted anymore when assigning them to a "url" property. Instead
they are resolved and possibly intercepted when used to access an actual
resource.

Fixes: QTBUG-76879
