chore: reorder mvfderiv lemmas (#43987) Previously, there was a section of lemmas about mvfderivWithin, then a corresponding section about mvfderiv. Ensuring these sections matched was a bit cumbersome, as one had to scroll back and forth all the time. Instead, move a lemma mvfderiv_foo right after its counterpart mvfderivWithin_foo. (Usually, this matches how it is proved also.) This matches the structure in e.g. the file about mfderiv.
