Motivation for this change

Split from #2023.

These lemmas make a small theory for boundedness properties of the form [bounded f x | x in A], which is notably useful for applying measurable_bounded_integrable.

Checklist
  • added corresponding entries in CHANGELOG_UNRELEASED.md
  • added corresponding documentation in the headers

Merge policy

As a rule of thumb:

  • PRs with several commits that make sense individually and that
    all compile are preferentially merged into master.
  • PRs with disorganized commits are very likely to be squash-rebased.

This looks like desirable lemmas. I changed the naming to shorter names in particular because range is a notation with a slightly different meaning (image of the whole set). There is also a misuse of the suffix P which is usually for equivalences. What do you think?
