The doc of scx_layered `Opt` is out of sync.
Implement attribute macro #stat_doc to generate doc from the `desc`
property.
Apply #stat_doc to `LayerStats` and `SysStats in scx_layered.

Exposes an option --monitor-no-dbus in scx_loader that will monitor CPU
utilization and start scx_lavd when any CPU exceeds 90% for more than 5
seconds. scx_lavd will be terminated if all CPUs are below 90% for
more than 30 seconds. When this flag is specified, scx_loader's
dbus functionality is not utilized.
Rust build was using two separate workspaces - rust/ and scheds/rust.
There's no reason to separate them and it makes doc generation tricky. Use
single top level workspace so that we can drive all rust building from
cargo.
