Fix sky_tools build command to look for package-root in global args

Also refactors the command line assembling to make a bit more sense.

Fixes #53

This makes the 'package-root' option universal for sky_tools and configures the
ArtifactStore with it statically at startup. The actual sky_engine revision
is computed on demand.

run_mojo: Add --mojo-release and --mojo-debug flags.

The flags control which build of mojo to run (Debug or Release).
Default is Release.

Make cached artifact location mirror local builds more closely

Refactor all the commands to be Commands from the Args package.  Also use CommandRunner for the top-level command.

sky_viewer.mojo no longer needs a window manager embedding as of
sky_engine 0.0.27, so this updates the sky_tools run_mojo command so it works

broken combinations but that needs to happen on the sky side.
