Some oss-fuzz bugs (like the linked one) would not reproduce in Skia proper due to the fact that there were subtle overloads of the various Fuzz::next() methods in FuzzCanvas.cpp that were pulled in in Skia proper, but not oss-fuzz. This puts all of them in to FuzzCommon.h and makes the matrix and rrect ones opt-in (fuzz_matrix, fuzz_rrect). Additionally, this renames fuzz.cpp -> FuzzMain.cpp so we can properly include Fuzz.cpp in oss-fuzz without having two mains.
