Revert "Revert "Revert "Redefine the meaning of sample counts in GPU backend."""
This reverts commit d0d7270fcc32546005b8e847df516cb11592cd30. Revert "More sample count cleanup:" This reverts commit d653cac70ed17983125ceed053138c09f1401846. Revert "Add new GrContext queries for imagability, surfacability, and max sample count of color types" This reverts commit 85ae7159c9c8a9186a4c7e74304eabb35bca9a79.
