internal: Update rustc_pattern_analysis dependency

Just bumping the dependency, as I've been making API changes over on the rustc side. More API changes incoming in the coming weeks.

One benefit of this: we no longer abort in the `DeconstructedPat: Debug` impl, which means we can use `tracing` to investigate issues.
