We had several defines around the code base that were not very descriptive. Additionally, we had a patch of extra runtime restrictions living in oss-fuzz that were applied when fuzzing over there for some fuzzers. This has all be consolidated and controlled via the defines documented in site/dev/testing/fuzz.md As such, we can remove one of the patches that is in oss-fuzz, taking us closer to being able to fuzz in the CI/CQ. PS 1 renames existing fuzz defines to the new schema. PS 2-3 backports skia.diff from oss-fuzz and changes those definitions to have the _GREATLY modifier. PS 5+ further condenses the defines so that there is one define for gating the runtime checks.
