Auto merge of #38357 - arielb1:deterministic-hash, r=michaelwoerister

make deterministic_hash host-architecture-independent

`DefPath::deterministic_hash` used to call `std::hash::Hash`, which depends on the current architecture in several ways, which would prevent metadata written on one host architecture from being successfully read on another one.

Use a hasher we control instead.

Fixes #38177.
