u2f: Move some u2f logic to common/ for testing
Since this is cr50's branch, there's no semantic difference whether
we put logic in board/cr50/u2f.c or common/u2f.c. EC's build system
doesn't quite allow unit-testing board-specific logic, so to unit-test
some of the crypto logic in board/cr50/u2f.c, things need to move
to common/u2f.c. There's no change in functionality.
There should also be no problem for merging/cherry-picking ToT changes
to cr50_stab, because any new u2f changes are made on cr50_stab only
and not on ToT.
BUG=b:172971998
TEST=make run-u2f
