init: add --manifest-depth for shallow manifest clonev2.29.5

People rarely care about the history of the manifest repo.  Add a
parameter to specify depth for the manifest.

For now, make the default behavior the same as the current behavior.  At
a future date, the default will be changed to 1.  People who need the
full history should begin passing --manifest-depth=0 to preserve the
behavior when the default changes.

We can't reuse the existing --depth option because that applies to
all projects we clone, not just the manifest repo.
