As discussed in #7748 (comment), we need to compare scalars approximately in some scenarios.

Also:

  • Fix comparison of same-pointer NaN values
  • Fix scalar comparison result when both inputs are null (ARROW-8956)
  • Fix scalar kernel result type when result is null scalar

I more or less rewrote this PR entirely as I identified other issues that were entangled with this one, and added a bunch of tests.
