feat(nix/lazy-deps): Add function to generate lazy binary dispatcher r/3996
There is a reoccuring problem in readTree-type repositories that use
nix-shell, where evaluation of the full set of dependencies that
should be made available to users takes a noticeable amount of time,
slowing down operations when `direnv` is involved.

In depot, we have so far fixed this by maintaining a manual `//bin`
directory which contains a set of symlinks to a central dispatch
script that can dispatch to various tools in depot lazily.

This script can instead be generated ad-hoc by Nix (pretty fast if we
can make assumptions like `git` and `nix-build` existing on user's
machines already) and added to $PATH.

The function introduced in this commit implements the logic for that.
The structure of the script is based on the existing
`//bin/__dispatch`.

This does not yet switch depot's envrc to use this new method of
installing dependencies lazily.
