rHG7f5410dfc8a6: rust-dirstatemap: add missing @propertycache
Summary

While investigating a regression on hg update performance introduced by the
Rust dirstatemap, two missing @propertycache were identified when comparing
against the Python implementation. This adds back the first one, that has
no observable impact on behavior. The second one (nonnormalset) is going to
be more involved, as the caching has to be done from the Rust side of things.
