feat(measure_theory): induction principles in measure theory (#3978) This commit adds three induction principles for measure theory

  • To prove something for arbitrary simple functions
  • To prove something for arbitrary measurable functions into ennreal
  • To prove something for arbitrary measurable + integrable functions. This also adds some basic lemmas to various files. Not all of them are used in this PR, some will be used by near-future PRs.
