chore: move all 3p buildRustCrate derivations to //third_party r/2419

Profpatsch and me are basically the only users of
depot.users.Profpatsch.writers.rustSimple*. To pull in the odd
dependency we usually use buildRustCrate which is rather convenient.
However we've picked up the bad habit of inlining these in a let
somewhere instead of managing them in a more central location although
there has been an (unsuccesful) attempt at this in
//users/Profpatsch/rust-crates.nix.

This CL moves all buildRustCrate based derivations into
third_party.rust-crates and deletes any duplicate derivations we have
accumulated in the tree.
