rust: add logging utils

This change adds the `log` crate, the community-approved logging facade backed
by Rust core developers as well as the logging-consumer crate `simple_logger`
to build a foundation for logging from Rust.

Using this setup allows us to choose how to log depending on the way `hg-core`
is used: if it's within the context of `hg-cpython`, we might not want to use
it the same way as with a direct cli for example.
