Subject: Revert "Revert "Revert "Revert "Redefine the meaning of sample counts
 in GPU backend.""""

This reverts commit 18c52a7b52211de5d0dcd86dc048adef758c6c75.

Also relands "More sample count cleanup:" and "Add new GrContext queries for imagability, surfacability, and max sample count of color types"
