fix: Include WalletContext in EIP-7715 requests

[jeffsmale90]

Explanation

wallet_requestExecutionPermissions and wallet_revokeExecutionPermissions (although the latter is not implemented in Extension) require the origin of the request in order to forward to the implementing snap.

When these methods were upgraded to JsonRpcMiddleware 2, the context was swallowed, so the origin became inaccessible. This change includes the context: WalletContext parameter in the call to the "process" function.
