XCM bridge hub pallet (will be deployed at bridge hubs) (#2213)

* XCM over bridge pallet (won't ever be merged to this repo): initial commit

* try both bridge-id and lane-id

* flush

* flush

* flush

* flush

* first prototype

* started working on xcm-over-bridge tests

* proper open_bridge_works test

* more open_bridge tests

* request_bridge_closure tests

* tests for close_bridge

* report_misbehavior tests

* renaming xcm-over-bridge ad xcm-bridge-hub: we'll have two similar pallets for dynamic lanes/fees support. One will be deployed at the bridge hub (xcm-bridge-hub) and another one (xcm-bridge-hub-router) at sibling/parent chains to send messages to remote network over the bridge hub

* added couple of TODOs

* moved BridgeQueuesState here + TODO for implementing report_bridge_queues_state + fmt

* fixing TODOs

* fixing TODOs

* moved bridge locations to primitives

* added a couple of TODOs

* ref issue from TODO

* clippy and spelling

* fix tests

* another TODOs

* typo

* LaneState -> force_close_bridge

* start_closing_the_bridge -> start_closing_bridge

* removed Closing bridge state, so now we only have the Opened -> optional temporary Closed state -> None

* spelling

* started prototyping suspend+resume on misbehavior

* continue prototyping

* more tests for open_bridge

* more tests for close_bridge

* more tests for report_misbehavior

* started tests for resume_misbehaving_bridges

* implemented tests for resume_misbehaving_bridges

* remove UnsuspendedChannelWithMisbehavingOwner because now, when all bridges are resumed at once + we assume that the inbound XCM channel is suspended immediately it is no longer actual

* added TODO

* add comment re misbehavior reporter if he's associated with the bridge owner

* ignored clippy

* fmt

* use versioned XCM structs in public interfaces and storage + Box XCM locations where possible

* spelling

* removed TODO in favor of paritytech/parity-bridges-common#2257

* LocalChannelManager -> LocalXcmChannelManager

* removed code specific to #2233, because it isn't the only option now

* removemisbehavior mentions

* also temporary (?) remove BridgesByLocalOrigin because the storage format will likely change to be able to resume bridges from the on_iniitalize/on_idle

* AllowedOpenBridgeOrigin -> OpenBridgeOrigin

* - TooManyBridgesForLocalOrigin

* use bridge_destination_relative_location in args

* better impl of strip_low_level_junctions

* get rid of xcm_into_latest

* clippy

* added #![warn(missing_docs)] to new crates
