refactor(tvix/eval): insert storeDir "builtin" in eval startup r/5887

Instead of using a suspended native thunk, calculate and optionally
insert the storeDir builtin when the VM is constructed.

We already have the IO handle available at this point and can just
check whether a storeDir is present, and insert its absolute value as
a builtin.
