* Catch native panics when executing the wasm runtime

As with the native runtime, we now catch all native panics when we
execute the wasm runtime. The panics inside the wasm runtime were
already catched before by the wasm executor automatically, but any panic
in the host functions could bring down the node. The recent switch to
execute the native counterpart of the host function in `sr-io`, makes
this change required. The native `sr-io` functions just `panic` when
something is not provided or any other error occured.

So, instead of:
`type ALL_MODULES = (Module1, Module2, Module3)`;
Generate it like this:
`type ALL_MODULES = ((Module1, Module2), Module3,);`

This should make `construct_runtime!` support an "unlimited" number of
modules.
