Add fake automotive vin number function (#1879)

[cyanghsieh]

What does this change

base on https://en.wikipedia.org/wiki/Vehicle_identification_number to create fake vin number data function.

What was wrong

new provider function

How this fixes it

Note: I'm not quite familiar with pytest module, therefore I'm not quite confident on creating a new auto test flow for this vin function. Please forgive me.

This is cool! I am also interested in using this feature, so if needed, I'd be happy to collaborate on building the tests for the feature.

I'll need tests before I can merge this.

Looks like @cyanghsieh beat me to it anyways...thanks!

The only thing I wonder if is test_vin should be outside of class _SimplyAutomotiveTestMixin. Looks like running as is will run the same exact test for every provider, as it does not depend on any attributes the same way that test_license_plate does. But I'm also not familiar with the overall test strategy of this repo, and maybe this is what it should do?

I think that's ok for now. But we should think of a way to mark methods as locale-independent.

Thank you!
