feat(Cdk-FocusTrap): ability to add more overlay detect on EventListenerFocusTrapInertStrategy

[keatkeat87]

Feature Description

currently EventListenerFocusTrapInertStrategy only base on "div.cdk-overlay-pane" to detect the focus is inside overlay. but it is not enough when we using third party plugin or our own overlay.

Use Case

for example using @tinymce/tinymce-angular it not depend on angular/cdk, so there is no overlay. but it have own implement overlay feature.

for workaround we can totally override a strategy for the case. but maybe angular team can consider add a easy way for that.

Adding a selector as an option will definitely solve this case, but it'll be a little clunky as an API. A more long term solution might be to make the focus trap less aggressive in recapturing focus.
