Support 'datetime' and 'datetime-range' filter variants

[noam3127]

I'm wondering if there's any interest in having 'datetime' and 'datetime-range' filter variants. My team has a use-case for this. These would be almost identical to the existing 'date' and 'date-range' variants, but using @mui/x-date-pickers/DateTimePicker instead of @mui/x-date-pickers/DatePicker.

I can try making a PR if others deem this feature useful as well.

A simple PR with as much code reuse as possible would be welcome
