Also make `f`/`f'` arguments implicit in all versions of Rolle's Theorem. Fixes #4830 ## API changes - `exists_Ioo_extr_on_Icc`: - generalize from functions `f : ℝ → ℝ` to functions from a conditionally complete linear order to a linear order. - make `f` implicit; - `exists_local_extr_Ioo`: - rename to `exists_isLocalExtr_Ioo`; - generalize as above; - make `f` implicit; - `exists_isExtrOn_Ioo_of_tendsto`, `exists_isLocalExtr_Ioo_of_tendsto`: new lemmas extracted from the proof of `exists_hasDerivAt_eq_zero'`; - `exists_hasDerivAt_eq_zero`, `exists_hasDerivAt_eq_zero'`: make `f` and `f'` implicit; - `exists_deriv_eq_zero`, `exists_deriv_eq_zero'`: make `f` implicit.
