[Feature Request] Calendar date picker

[MelvinFrohike]

Problem to solve

Our application needs a picker that can select a date without a year, e.g. for selecting annual holidays.
We've been able to co-opt the VDatePicker to do this using the following steps:

1. set min and max dates of 2024-01-01 & 2024-12-31 (2024 as it is a leap year)
2. strip the year from the returned date
3. set the weekday-format prop to null to remove the weekday names from the picker.
4. set the first-day-of-week prop dynamically so that the first day of each month is chosen (moving the first to the top left for each month)
5. set the header-date-format prop to only show the month's name but strip the year

Unfortunately, this doesn't work with Vuetify 3 anymore as neither the first-day-of-week prop nor the header-date-format prop is available. With steps 1 - 3 still working, it is usable but makes for a confusing UI as the user clearly sees the year 2024 while expecting to select a date without a year.
Another drawback with Vuetify 3 is that the picker opens on the current month whereas before it opened on the month of the min-date, which means users will have to manually move into the correct year.

Proposed solution

I would love to have either a dedicated picker for calendar days without years, or a prop/mode in VDatePicker that configures it for that use-case. Alternatively, reintroducing the props first-day-of-week & header-date-format would allow me to co-opt the VDatePicker again, although this still feels like a dirty hack.
