Subject: [PATCH] chore: fix mdc-menu prototype not working with ivy

Currently the `MatMenu` from the `@angular/material-experimental/mdc-menu`
entry-point does not with Ivy as the base class (`MatMenu`) is not decorated and
therefore Ivy is not able to generate the proper factory for the constructor. In order
to fix this, we just create a pass-through constructor which ensures that dendency
injection properly works.
