dirstate-tree: Make Rust DirstateMap bindings go through a trait object

This changeset starts a series that adds an experiment to make status faster
by changing the dirstate (first only in memory and later also on disk) to
be shaped as a tree matching the directory structure, instead of the current
flat collection of entries. The status algorithm can then traverse this tree
dirstate at the same time as it traverses the filesystem.

We (Octobus) have made prototypes that show promising results but are prone
to bitrot. We would like to start upstreaming some experimental Rust code that
goes in this direction, but to avoid disrupting users it should only be
enabled by some run-time opt-in while keeping the existing dirstate structure
and status algorithm as-is.

The `DirstateMap` type and `status` function look like the appropriate
boundary. This adds a new trait that abstracts everything Python bindings need
and makes those bindings go through a `dyn` trait object. Later we’ll have two
implementations of this trait, and the same bindings can use either.

#if gettext

Test translated help message

str.lower() instead of encoding.lower(str) on translated message might
make message meaningless, because some encoding uses 0x41(A) - 0x5a(Z)
as the second or later byte of multi-byte character.

For example, "\x8bL\x98^" (translation of "record" in ja_JP.cp932)
contains 0x4c (L). str.lower() replaces 0x4c(L) by 0x6c(l) and this
replacement makes message meaningless.

This tests that translated help message is lower()-ed correctly.
