Replace them by the equivalent `simp` call and squeeze that. We leave `field_simp` calls slower than roughly 150ms in place. A few calls cannot easily be replaced; we leave these alone as well.

Speeds up all affected files, including `Euclidean/Circumcenter` by 4%, `Inversion/Basic` by 27% and `Triangle` by 52%.

    perf(Geometry/Manifold/Instances/Sphere): speed up (#15488)

    Speed up the file by 9% by doing the following
    - squeeze simps where the full form is short and this is a clear win
    - "squeeze" three really slow field_simp calls: replace them by the equivalent simp invocation and squeeze that
    - avoid one slow `convert`
    - squeeze two really slow nlinarith calls (they're still slow, but much better)
    - replace one congr! by congr

    This is a reduced version of #13456, which is hopefully less controversial.

    fix(fun_prop):  few bug fixes for fun_prop (#11092)

    Bug fixes
    1. Fix infinite loop triggered by `(by fun_prop : ?m)`
    2. Support for multiple lambda theorems. For example `ContinuousOn` has multiple versions of composition theorem.
    3. Support for special constant lambda theorem. For example `IsLinearMap R fun _ => 0` should be registered as constant lambda theorem
    4. Improved error messages when trying `fun_prop` on non-fun_prop goal
    5. Improved error messages when missing lambda theorems

    feat(Algebra/Homology): signs for the associativity compatibility of the total complex (#15719)

    This PR introduces a typeclass `ComplexShape.Associative` which takes as inputs six complex shapes `c₁`, `c₂`, `c₃`, `c₁₂`, `c₂₃` and `c`, and asserts compatibilities of signs for the associativity of the total complex of a triple complex. It shall also be used in the construction of the associator isomorphism for the tensor product of homological complexes.

    feat(Algebra/Homology): action of the flip of a bifunctor on homological complexes (#11713)

    We construct an isomorphism `mapBifunctor K₂ K₁ F.flip c ≅ mapBifunctor K₁ K₂ F c` when `F` is a bifunctor, and `K₁` and `K₂` are two homological complexes. This is under the assumption of a certain instance of `TotalComplexShapeSymmetry` which provides compatible signs for this isomorphism.
