Reland "Replace SK_ARRAY_COUNT with std::size() all the rest"

This is a reland of commit f838f6f62f62012c2b7d78f41901e4fdcfc21181

Original change's description:
> Replace SK_ARRAY_COUNT with std::size() all the rest
>
> Added changes to IWYU_mapping.imp to allow std::size. This
> requires multiple entries because std::size can be defined from
> any number of files. Please see the following for reference:
> https://en.cppreference.com/w/cpp/iterator/size
>
> Please check that I got all the includes from the documented list.
