This reduces lock contention a bit for incremental compilation. #60035 gets rid of the locks, but is much larger and probably won't land until @michaelwoerister returns. This reduces clean incremental times for winapi from 18.37s to 16.43s on 16 threads / 8 cores.

Based on #61779.

Auto merge of #62038 - Zoxc:pre-gc-dep-graph, r=<try>
[WIP] Make dep node indices persistent between sessions

This makes marking dep nodes green faster (and lock free in the case with no diagnostics). This change is split out from #60035.

Unlike #60035 this makes loading the dep graph slower because it loads 2 copies of the dep graph, one immutable and one mutable.

Based on #61845, #61779 and #61923.
