Warn in QQmlJSTypePropagator::generate_LoadQmlContextPropertyLookup()
about usages of context properties that were found. Also treat context
properties as var.
Add the (C++) location of the "setContextProperty()" call to the
warning, and also hint that a property is assumed to be a context
property when inside a top-level component (capital C Component, inline
component or implicitly wrapped as component) because it is not
declared as required property.
Still print the accompanying unqualified warnings next to the new
context property warning.
Add a test.
Later patches will add the support to qmlls and qmllint by passing
the workspace folders to the new functionality.
