dirstate-tree: Empty shell for a second Rust DirstateMap implementation

For background see description of the previous changeset
"Make Rust DirstateMap bindings go through a trait object".

Add an empty shell for a opt-in second Rust implementation of the
`DirstateMap` type and the `status` function. For now all methods panic.
This can be seen in "action" with:

    ./hg status --config experimental.dirstate-tree.in-memory=1
