Add nondiff rules for one ones zero zeros

[niklasschmitz]

Porting nograd rules for one, ones, zero, zeros from Zygote https://github.com/FluxML/Zygote.jl/blob/master/src/lib/array.jl#L11

Follow-up to #252

This was also mentioned in FluxML/Zygote.jl#780 by @oxinabox. Should these rather return ZeroTangent() than NoTangent() ?

I suppose one and zero need ZeroTangent() (see https://juliadiff.org/ChainRulesCore.jl/dev/FAQ.html#faq_abstract_zero)

but they work almost identically so I would favour the simplicity of using a macro over being pedantic in this case.

Thanks for the PR! Will merge when CI passes. Just FYI, it's possible to commit the code suggestions all at once, which prevents CI from running for each suggestion. I think there is a limit to how many jobs can be run per organisation at the same time, and ChainRules tests take a while so a queue forms sometimes.

Thanks @mzgubic !
