We generalize dim_zero_iff_forall_zero to [nontrivial R] [no_zero_smul_divisors R M].

If you see a more general class to consider let me know.

I don't know an obvious class to replace no_zero_smul_divisors, and if someone finds it later on, they can make a new PR and I'm happy to review that. Let's Get This Merged!
