pat_analysis: Don't rely on contiguous `VariantId`s outside of rustc

Today's pattern_analysis uses `BitSet` and `IndexVec` on the provided enum variant ids, which only makes sense if these ids count the variants from 0. In rust-analyzer, the variant ids are global interning ids, which would make `BitSet` and `IndexVec` ridiculously wasteful. In this PR I add some shims to use `FxHashSet`/`FxHashMap` instead outside of rustc.
