Disables opening blast doors & shutters by riding into them (#95102)

## About The Pull Request

Swaps the proc being called on doors in the riding component's
`vehicle_bump()` proc from `bumpopen()` to `Bumped()`, causing relevant
checks to be undergone, most importantly the check for
`can_open_with_hands`. Due to the way vehicles are bumped by their
drivers and thus cause their drivers' `last_bumped` to be set, the
riding component now tracks its own `vehicle_last_bumped` & resets its
occupants' `last_bumped` when bumping doors, given the vehicle is off
bump cooldown.

`vehicle/sealed` gets to keep `bumpopen()` because they give
`TRAIT_HANDS_BLOCKED`, but they check for `can_open_with_hands` now.

Additionally, just for consistency's sake, firelocks' previous
`bumpopen()` override has been removed and replaced with
`can_open_with_hands`.

## Why It's Good For The Game
