Bump Propolis (#9726)

relevant propolis change since last bump (plus some commits that are
docs/tools-only, and disabling doorbell buffers + reverting the
disable):

* nvme: CQ db_buf EventIdx should slightly lag CQ tail

this fixes what we ended up finding as an associated issue in
oxidecomputer/propolis#1008, where guests
could end up having submitted disk operations we were told to process
and subsequently never did.
