Auto merge of #45476 - Xanewok:fingerprint-disambiguator, r=michaelwoerister

Browse source 
Use 128 bit instead of Symbol for crate disambiguator

As discussed on gitter, this changes `crate_disambiguator` from Strings to what they are represented as, a 128 bit number.

There's also one bit I think also needs to change, but wasn't 100% sure how: [create_root_def](f338dba297/src/librustc/hir/map/definitions.rs (L468-L482)). Should I change `DefKey::root_parent_stable_hash` to accept `Fingerprint` as crate_disambiguator to quickly combine the hash of `crate_name` with the new 128 bit hash instead of a string for a disambiguator?

r? @michaelwoerister

EDIT: Are those 3 tests `mir-opt` failing, because the hash is different, because we calculate it a little bit differently (storing directly instead of hashing the hex-string representation)? Should it be updated like in #45319?
