dismissableMask and closeOnEscape for Dialog

[ilyavaiser]

It would be nice to have built-in support for this behavior.

PrimeFaces, PrimeNG and PrimeReact have this, we sure can add it to Vue as well.

Hi everyone!

It would be nice if there was a way to close the dialog when the mask is clicked. For example, Vuetify's <v-dialog> emits a @click:outside event when its mask is clicked that is very useful.

Thank you for your great job!
