.sync/rust_config/Makefile.toml: Add check task (#241)

The VS Code `rust-analyzer` plugin uses `cargo check` to find
problems. We use custom flags/target info with `cargo make`.

This adds a `cargo make check` command that reuses similar
flags to our build so the check results are similar. `check_json`
is added to be used by tools like VS Code that need JSON
output.
