UnresolvedFunctionImport for Moonbeam Runtimes

[albertov19]

According to -> AcalaNetwork/chopsticks#575

When using Moonbeam in the latest version of Chopsticks, and setting allow-unresolved-imports to false, you get:

npx @acala-network/chopsticks@latest -c moonbeam --allow-unresolved-imports false
Logs:

panicked at 'called `Result::unwrap()` on an `Err` value: VirtualMachine(UnresolvedFunctionImport { function: "ext_panic_handler_abort_on_panic_version_1", module_name: "env" })', src/task.rs:133:6

Chopsticks devs suggested that Moonbeam's new runtime has functions unknown to smoldot

[tomaka]

This indeed needs fixing in smoldot, but I want to point out that allow_unresolved_functions: true is fundamentally the correct setting when it comes to parachains, as parachains are free to add their own custom host functions.

[librelois]

@tomaka I get the same error even with allow_unresolved_functions: true.

[librelois]

@tomaka @albertov19 the host function PanicHandler::abort_on_panic is never called by our runtime because it's disabled by the rust feature disable_panic_handler.
So, for some reasons the chopsticks parameter allow-unresolved-imports: true is not taken into account, the problem may come as much from chopsticks as from smoldot.
