 In this file we define smooth structures that build on Lie groups. We prefer using the term smooth
 instead of Lie mainly because Lie ring has currently another use in mathematics.

chore: cleanup Mathlib.Init.Data.Prod (#6972)

Removing from Mathlib.Init.Data.Prod from the early parts of the import hierarchy.

While at it, remove unnecessary uses of Prod.mk.eta across the library.

This has nice performance benefits.
