Update Interoperability LIPs

[ricott1]

Update Interoperability LIPs to add events and error handling.

• throw errors rather than return false/true
• Fix typo in https://github.com/LiskHQ/lips/blob/main/proposals/lip-0049.md#executing-registration-message (should be channel not chainAccount 🆗
• check images against dark background
• update this section: https://github.com/LiskHQ/lips/blob/main/proposals/lip-0053.md#liveness-of-partner-chain 'partner chain' --> 'sidechain' and explain that this is done only on the mainchain 🆗
• explain more clearly that mainchain is always live: https://github.com/LiskHQ/lips/blob/main/proposals/lip-0045.md#islive 🆗
• set idxs to uint32 in LIP54 for message recovery params 🆗
• fix storeKey(MAINCHAIN_ID) for the channel data substore in https://github.com/LiskHQ/lips/blob /aced79e3a90c893f25c8f0735ce73732f17cced6/proposals/lip-0043.md#execution-1 🆗
• CCU LIP within the inboxUpdate Validity, STORE_PREFIX_OUTBOX -> STORE_PREFIX_OUTBOX_ROOT 🆗
• LIP 0043: update TAG_CHAIN_REG_MESSAGE to MESSAGE_TAG_CHAIN_REG 🆗
• bounce and message recovery does not swap sending and receiving anymore. As a consequence, CCU on sidechains check the receivinChainID only if the status is ok
• message fees are assigned by an explicit call to the token module.
• if beforeCCMApply fails, state is reverted
