Issue DM-2193: Add assertXNearlyEqual to afw
We often want to compare two WCS for approximate equality. afw/image/testUtils has similar functions to compare images and masks and I would like to add one for WCS This ended up being expanded to adding functions for many afw classes (not yet including image-like classes, though existing functions in image/testUtils for that purpose should probably be wrapped or rewritten on a different ticket)
