Refactor: Use InvokeContext in all Syscalls

[Lichtso]

Problem

Not all SyscallObjects have invoke_context: Rc<RefCell<&'a mut dyn InvokeContext>>.
Some access the individual properties of InvokeContext in bind_syscall_context_objects() which:

• Necessitates these individual properties to be wrapped in Rc and RefCell even though the entire &mut InvokeContext is already wrapped
• Makes it harder to remove the dyn Trait of InvokeContext because of the lifetimes of the involved references

Summary of Changes

• Moves access to the individual properties of InvokeContext from bind_syscall_context_objects() into the matching SyscallObject::call().
• Adjusts the syscall tests so that all mock an InvokeContext.
