cli: add mud build command

[holic]

We currently have this kinda weird separation between the commands run for building a MUD project and the commands used by deploy, where an update to one may miss another (see #1801).

We could simplify the build script in projects by exposing a mud build that knows what to do (tablegen + worldgen + forge build + abi-ts) and use that ahead of all deploys (until we add better incremental change detection).
