feat(tvix/eval): compile `with` expression r/4551
Adds an additional structure to the compiler's scope to track the runtime "with stack", i.e. the stack of values through which identifiers should be dynamically resolved within a with-scope. When encountering a `with` expression, the value from which the bindings should be resolved is pushed onto the stack and tracked by the compiler in the "with stack", as well as with a "phantom value" which indicates that the stack contains an additional slot which is not available to users via identifiers. Runtime handling of this is not yet implemented.
