Ctrl click refactor (#83784)

## About The Pull Request
Same idea as #82656 but for ctrl click & ctrl shift click cause why not

- Does your signal & `can_perform_action()` checks using
`interaction_flags_click` flags before delegating the event down to
`ctrl_click()` proc.
- The one new change now is that `ctrl_click()` proc is now blocking,
meaning returning `CLICK_ACTION_SUCCESS` or `CLICK_ACTION_BLOCKING` will
stop the object from getting grabbed/pulled. So remember to return these
values if you want to stop the grab action or return `NONE` if you want
to process the click but still want the object to get grabbed as well
