This caused us to lose our gn check certification. :(
Turns out gn check was just ignoring all the header
paths it didn't understand and so gn check passing
for sky wasn't meaning much. I tried to straighten
out some of the mess in this CL, but its going to take
several more rounds of massaging before gn check
passes again. On the bright side (almost) all of
our headers are absolute now. Turns out my script
(attached to the bug) didn't notice ../ includes
but I'll fix that in the next patch.

Instead of using a custom ::attach to do post insertion work
when assigning the image resource to the RenderImage, we should
just fix the logic inside RenderImage to be able to handle
not being in the tree yet when the resource is first set.
Soon attach will not be virtual anymore.
I also made RenderImage final and most methods private as there
are no longer subclasses.
