fix: WellFounded preprocessing: use dsimp (#7409)
This PR allows the use of `dsimp` during preprocessing of well-founded
definitions. This fixes regressions when using `if-then-else` without
giving a name to the condition, but where the condition is needed for
the termination proof, in cases where that subexpression is reachable
only by dsimp, but not by simp (e.g. inside a dependent let)

Also fixes some preprocessing lemmas to not be bad simp lemmas (with
lambdas on the LHS, due to dot notation and unfortunate argument order)

This fixes #7408.
