Making MaterializationResponsibility instances immovable allows their associated VModuleKeys to be updated by the ExecutionSession while the responsibility is still in-flight. This will be used in the upcoming removable code feature to enable safe merging of resource keys even if there are active compiles using the keys being merged.
