tvix/store/directoryservice: give traverse_to a better name, rewrite in non-recursive
#270

See discussion in https://cl.tvl.fyi/c/depot/+/8568.
The naming is a bit bad (maybe something with find_ or descend_ might make more sense?).
It should also be possible to rewrite this in an iterative fashion, and compare the two implementations for readability.
