don't inherit allowed deprecation from parent modules

Browse Source 
Inheriting allow-deprecation from parent modules doesn't make too much
sense, so instead make them default to disallow unless otherwise
specified. This allows build system to avoid redundant
`-fno-allow-deprecated` args.

This makes the generated CLIs smaller, and makes zig1.wasm update not
needed.

Also represented `is_root` differently (moved to field of graph).
