This commit removes some unused parameters, properties and variables in various `@angular/upgrade` functions.
Previously, due to the way the AngularJS and Angular clean-up processes interfere with each other when removing an AngularJS element that contains a downgraded Angular component, the data associated with the host element of the downgraded component was not removed. This data was kept in an internal AngularJS cache, which prevented the element and component instance from being garbage-collected, leading to memory leaks. This commit fixes this by ensuring the element data is explicitly removed when cleaning up a downgraded component. NOTE: This is essentially the equivalent of angular#26209 but for downgraded (instead of upgraded) components. Fixes angular#39911 Closes angular#39921
