fix(tvix/store): Fix FUSE support on MacOS r/6687
This partially fixes b/312 and gets FUSE to work again on MacOS.

It is mostly small type changes and an update to fuse-backend-rs because
upstream currently doesn't work with MacFuse. It also sets the default
FUSE thread count on MacOS to 1 because otherwise the mount command will
hang when shutting down as only one thread gets ENODEV and all the others
just keep blocking.
