E.W.Ayers 8311c88fd0 refactor: extract methods from Lean.Meta.transform
Lean.Meta.transform is created with a series of recursive
visit functions. However these visit functions are useful
on their own outside of transform for traversing expressions.

This commit moves the visit functions outside the main function.
