Add Bridges to xcm-emulator (#2812)

* rename bridge hub + BridgeMessages type * bridge base * bridge string approach * add decl_test_bridges macro * outbound lanes on the way * get & dispatch mock bridge done * fix bridge errors + log::debug for messages * clean up * update source OutboundLaneData * rococo & wococo added * sender_receiver_accounts_parameter_types macro * sender_receiver_accounts_parameter_types macro 2 * fixed multi parachain + example on the way * working but router error * bridge working * refactor NetworkComponent * make it generic * working as generic * clean up * last bit * ".git/.scripts/commands/fmt/fmt.sh" * fix bridge hub handler name * ".git/.scripts/commands/fmt/fmt.sh" * add AssetConversion back for AssetHubWestend * Update xcm/xcm-emulator/src/lib.rs Co-authored-by: Squirrel <gilescope@gmail.com> * add LaneId wrapper * update substrate * fix wrapper conversion * remove duplicate in workspace * Revert "update substrate" This reverts commit 92e8f201ae433aed3f70b998ebd4c23d9168d0ee. * ".git/.scripts/commands/fmt/fmt.sh" --------- Co-authored-by: command-bot <> Co-authored-by: Squirrel <gilescope@gmail.com>
