Robert Phillips 079455c739 Make the GrSmallPathAtlasMgr a flush-time object
This will allow the small path renderer to be used w/ DDLs.

This is broken out of the omnibus CL:

https://skia-review.googlesource.com/c/skia/+/307776 (Split the small path renderer into record-time and flush-time pieces)
