Upload Crosschain Swaps Contract V2

Passing this proposal will upload an updated version of the Crosschain Swaps contract to the Osmosis chain. \n## Details \nThe set of contracts within the XCS bundle enables trades on Osmosis to be carried out remotely from another chain connected to Osmosis by IBC. \n\nVersion two of the contracts simplifies the usage of crosschain swaps by keeping registries with information about IBC channels used, denoms used on Osmosis, and when to use packet forward middleware vs. callbacks. \n\nThe Crosschain Swaps contract receives a token transfer from chain A, looks up the required information from the Crosschain Registry contract, interacts with the Swap Router contract to exchange the received token for a different token, and then forwards it to a destination address specified in the original transaction. \n\nThis instance then looks up the correct information to use from the linked instance of the Crosschain Registry contract and, using this, interacts with the Swap Router contract to exchange the received token for the desired token. \n\nThe resultant tokens are then forwarded to the address initially specified in the memo, be that a return to the address on Chain A or forwarding to an address on Chain C. \n\nFull Documentation: https://github.com/osmosis-labs/osmosis/tree/main/cosmwasm/contracts/crosschain-swaps \n## Contract information \nRelease: V2 \n\nCompiler Version: cosmwasm/workspace-optimizer:0.12.10 \n\nChecksum: 3839d7281088f0152f643d57854e0625fd709db151e6dfe12da02f00efc3477e \n\nCode repository: https://github.com/osmosis-labs/osmosis/tree/main/cosmwasm/contracts \n\nCommit ID: b90dfad7f2ab8ecdd2806cb51dfa9a72fb80a469 \n\nForum Thread: https://forum.osmosis.zone/t/upload-xcs-v2-contracts/335
