Draft: allow to set more than 4 digits pincode
this is a pending MR, do not merge yet as community discussion states that we should not by default remove the auto login and the dots placeholder. To allow to set a custom pin code length, we need to store the length when we change it -> lomiri-schema AcountService
fixes https://github.com/ubports/ubuntu-touch/issues/1027
Must be merged along with lomiri-system-settings-security-privacy!9 (closed)
