mb/google/nissa: Create sundance variant

Create the sundance variant of nissa reference board by copying the
template files to a new directory named for the variant.

Due to new_variant.py limitation that repo can no longer be used in
inside, created this CL manually following google suggestion.

BUG=b:328505938
TEST=util/abuild/abuild -p none -t google/brya -x -a
make sure the build includes GOOGLE_SUNDANCE
