[Feature Request] VDateInput should auto-fill separators while typing

[Jason5679]

Problem to solve

When using v-text-field with type="date", the date separator (dot) was always automatically present and the user could enter the date without manually typing separators. With the v-date-input component, the separator has to be entered manually by the user.

This creates a different user experience than our users are familiar with.

Proposed solution

It would be helpful if v-date-input supported an input-mask prop or automatically handled the date separators in the same way as .

Turned out a bit harder to handle substitution (typing within existing date string)
Needs more time in the oven
