refactor(LinearAlgebra): replace Submodule.restrictBilinear by BilinForm.restrict (#12045)

As discussed in this thread, there were 3 different definitions for the restriction of a bilinear form to a subspace. This PR deletes the definition Submodule.restrictBilinear, and replaces all its occurrences by the LinearMap.BilinForm.restrict one.

chore(LinearAlgebra): Introduce a LinearMap.BilinForm alias (#10632)

This is one of the steps in #10553.

Once we eliminate _root_.BilinForm, we can drop the LinearMap. prefix.

Requested on Zulip by me (2021), [by @kmill](https://leanprover.zulipchat.com/#narrow/stream/116395-maths/topic/.60bilinear_form.60/near/310675731) (2022), and perhaps one or two other places.

  • Redefine Set.seq as Set.image2. The new definition is equal to the old one but rw [Set.seq] gives a different result.
  • Redefine Filter.map₂ to use ∃ u ∈ f, ∃ v ∈ g, image2 m u v ⊆ s instead of ∃ u v, u ∈ f ∧ v ∈ g ∧ ...
  • Update lemmas like Set.mem_image2, Finset.mem_image₂, Set.mem_mul, Finset.mem_div etc

The two reasons to make the change are:

  • ∃ a ∈ s, ∃ b ∈ t, _ is a simp-normal form, and
  • it looks a bit nicer.
