Just make the ctx parameter of this function &mut vm::InternalCtx.

Then the definition of the ProtectedCaller trait needs to be changed. I doubt whether this is really needed.

Because CALL_WASM needs to setup a register containing memory information (base, bound) which is passed in as a paremeter.

Okay. Let's merge this and then discuss implementation later.
