Description

We created a merger for the Caip25Permission specification in order to enable wallet_addEthereumChain and wallet_switchEthereumChain to call to the PermissionController rather than the ApprovalController for incremental permission requests (i.e. for the permittedChains flow).

PRs implementing these changes
core: MetaMask/core#5283
extension: #30042

We also changed eth_requestAccounts and wallet_requestPermissions handlers to call the PermissionController, but we should now do the change to wallet_createSession handler as well and address this feedback on the Flask Multichain PR (at the moment this is only available on the Flask Multichain PR)
