Daniel Rainer 2f74785620 xtask: add initial setup ...

This is an initial implementation of the cargo xtask approach
https://github.com/matklad/cargo-xtask

For now, the only xtask is "check", which can be triggered by running
`cargo xtask check`. It is a thin wrapper around `build_tools/check.sh`.
