Create a bilinear map (represented as a map E →L[𝕜] F →L[𝕜] G) from the corresponding linear
map and existence of a bound on the norm of the image. The linear map can be constructed using
LinearMap.mk₂.
If you have an explicit bound, use LinearMap.mkContinuous₂ instead, as a norm estimate will
follow automatically in LinearMap.mkContinuous₂_norm_le.
