This is broken and I don't really like this behavior anyway

Using `object` causes errors if we disable `suppressImplicitAnyIndexErrors`

By overriding _register in this case, we could end up invoking this function on a subclass that had not actually been inited yet (when `_toDispose` has not been set). I believe the overriding was an accident, so the fix is to remove it

Fixing errors related to https://github.com/microsoft/TypeScript/issues/31380

* new reg service and always on mnemonics

* missed one

* use new node module and accessibility service

* add typings

* adopt accessibility service

* make it lazy
