MNT: Replace lazyproperty with cached_property in Python 3.8

See original GitHub issue

As @Mariatta pointed out in https://github.com/astropy/astropy/pull/8881#issuecomment-513956394 , we might be able to replace lazyproperty with cached_property that is new in Python 3.8. We also need to figure out the best way to support this for Python<=3.7 or wait until our Python minversion is 3.8.

Hmm, from a quick look, cached_property does not have the ability to have a setter or deleter - I definitely use the latter in my code. But perhaps we can upstream our implementations for those.

Indeed, though as discussed above, we have to be really careful, since the behaviour is rather different. Definitely not a search-and-replace!
