  • more backcompat options, about respectTransparency.types
  • a bunch of lemma deprecations, as usual
  • remove some letI/haveI by let/have when in Prop context: found by a new mathlib linter
  • remove some in fact superfluous have's
  • deprecated lemmas about mfderiv of spheres

This statement is slight defeq abuse, but that defeq was pre-existing --- not a reason to hold up this PR.

(Besides, the long-term proper fix is to make the main statement use IsSmoothEmbedding and IsImmersion form mathlib, which can have different constructors for "injective mfderiv" or "injective mvfderiv".)
