…asses (#23559) * fix(material-experimental/mdc-menu): ensure mat-mdc- prefix on all classes The MDC menu trigger had `.mat-menu-trigger` class because it was using the same directive as the non-MDC menu. This PR refactors the trigger and content directives to extend a common base class. * fixup! fix(material-experimental/mdc-menu): ensure mat-mdc- prefix on all classes * fixup! fix(material-experimental/mdc-menu): ensure mat-mdc- prefix on all classes * fixup! fix(material-experimental/mdc-menu): ensure mat-mdc- prefix on all classes (cherry picked from commit 771afd9)
