Kokkos::Array is fully missing in the wiki

[fnrizzi]

i don't see any entry about `Array un less I am missing it.

This relates to #6252

@nliber has PR in on array functions, and array deduction guides, among others. Can you give us a hand with this, Nevin?

QUESTIONS:

• How to document specializations?
• Should the specializations be on the same or diff pages?
• For the three template parameters, how to document examples? Which is to say, as people would use it, or the class as it exists?
  COMMENTS:
• View of a Kokkos::Array does not have special semantics, which is to say clarify semantics of Kokkos array
• Document the way the class is implemented, as well as how users should use it
• Provide warning that this class will change in the not too distant future?
• Make main page and then subpages for each of the specializations;
• Kokkos::Array header is not in containers, but put it there in the documentation, and note that the header is not in containers (because not device-construct-able)
  • If Array moved out, then might break dependencies in wider Kokkos Core
• In the near term, get some basic documentation in place, and iterate

@nliber - ping; what's the ETA on this work?

I was recently searching for some Kokkos::Array details and it's definitely still missing 😉
