Migrate missed pickers to new width system (#59693)

# Objective

- Fixes #59643.

## Problems

- Initial and minimum width was not migrated for all pickers.
- Some pickers had their width still determined by their wrapper. 
- Some pickers where not modals but did not have modal false set.

## Solution
- Migrate the pickers we missed.
- Remove the width being set on the div's wrapping the pickers.
- Set modal false on the missed pickers.
