Implement strict mode for qmldir modules

Allow a module's qmldir to contain a module directive, which when
present specifies 'strict mode' import processing.  In strict mode,
type registrations are only permitted into the namespace identified
in the qmldir file's module directive.  In addition, any type
registrations to that namespace originating from other modules are
treated as error conditions.

Task-number: QTBUG-26551
