Add extrinsic to improve position in a bag of bags-list (#9829)

* pallet-bags-list: Add `put_in_front_of` extrinsic

This PR adds the extrinsic `put_in_front_of` which allows the user to specify a `lighter` and `heavier` account within the same bag. The extrinsic will move `heavier` directly in front of `lighter`.  The parameter names refer to the fact that `lighter` must have a lower `VoteWeight` then `heavier`. 

In the ideal use case, where a user wants to improve the position of their account within a bag, the user would iterate the bag, starting from the head, and find the first node who's `VoteWeight` is less than theirs. They would then supply the `id` of the node as the `lighter` argument and their own `id` as the `heavier` argument.

* Test & Benchmarks

* Respect line width

* Remove List::put_in_fron_of tests; Remove AlreadyHigher error

* The dispatch origin for this call must be ...

* Add some periods

* Add back test to list module: put_in_front_of_exits_early_if_bag_not_found

* add test tests::pallet::heavier_is_head_lighter_is_not_terminal

* Cater for edge case of heavier being head

* Add ExtBuilder::add_aux_data; try to make some tests use simpler data

* Update frame/bags-list/src/list/tests.rs

* make insert_at_unchecked infallible

* Make it permissioned - only callable by heavier

* Add test cases for insert_at_unchecked

* Move counter update to insert_at; fix comments
