rust: Remove the compile-time 'dirstate-tree' feature flag

This code has compiler errors since it is not built on CI and nobody has been
working on it for some time.

We (Octobus) are still pursuing status optimizations based on a tree data
structure for the dirstate, but upcoming patches will use a run-time opt-in
instead of compile-time, so that at least corresponding Rust code keeps
compiling when other changes are made.
