[IMP] web: add smart date input on date field

This commit adds smart date inputs for date and datetime fields.

The goal of smart date input is to provide the user some shortcuts
when setting dates.

The rule is [+-]\d+[dwmy]?
So we can enter inputs like:
  +3  to have today + 3 days
  -2w to have today - 2 weeks
  +1y to have today + 1 year
  +5m to have today + 5 months
  -4d to have today - 4 days

closes odoo/odoo#55602
