Evaluate arguments passed to vmmap

[clubby789]

Description

Attempts to parse and eval an argument passed to vmmap.

This makes vmmap $rip, for example, work.

This is useful as it is easier to look up the memory section a pointer contained in a register/variable points to. It's also more consistent with commands like dereference
