mb/google/hatch: split up hatch and puff baseboards

The hatch and puff baseboards have diverged enough to where it makes
more sense to split them into separate boards. Copy the mb/google/hatch
directory into a new dir 'puff' and strip out all boards and items
related to the hatch baseboard. Remove all puff-related items from the
original hatch directory. Clean up and alphabetize Kconfig selections.

Test: build and boot akemi hatch variant and wyvern puff variant.
