chore(tvix/eval): thread current slot index through compiler r/4664

While compiling local bindings, we now know the stack slot of the
value currently being compiled.

This will let us determine whether an upvalue can be captured directly
or whether it needs to wait for a synchronisation point at which the
upvalue can be instantiated.

This machinery lets us avoid unnecessary work at runtime when
instantiating closures that actually do not need complicated recursive
resolution.

This change itself introduces no new functionality, but since the
threading is noisy it is split out as a separate change.
