feat(Logic/Equiv/Defs): add coe_ofBijective simp lemma

[b-mehta]

We have the applied version of this, but that doesn't fire on the coerced equiv

• The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
• The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

Doesn't having this prevent Equiv.apply_symm_apply firing on ofBijective f hf ((ofBijective f hf).symm x)? I think we often avoid making such lemmas simp for this reason.

	@[simp] lemma coe_ofBijective (f : α → β) (hf : Bijective f) : ⇑(ofBijective f hf) = f := rfl
	lemma coe_ofBijective (f : α → β) (hf : Bijective f) : ⇑(ofBijective f hf) = f := rfl

Doesn't ofBijective_apply already do that?

[b-mehta]

Exactly, and there are already loads of @[simp] lemmas like this in mathlib, eg QuaternionAlgebra.coe_addEquivTuple, Equiv.coe_constVSub, WithZero.coe_expEquiv_apply (which I found by just looking through search results in alphabetic order.
