493f89e577 [fuzz] Standardize, document, and backport fuzzing defines.
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.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

No-Presubmit: true

consistent.

0b8fcbcfa3 Add fuzzers for SkAndroidCodec & incrementalDecode
Fuzz SkAndroidCodec to help to catch errors in both incrementalDecode
and scanlineDecode. Try a variety of sample sizes, but cap it at 64.
Though sometimes larger sample sizes are used, the lower ones tend to
more common. Also draw the resulting bitmap to verify that we
initialized all pixels.

Independently test incrementalDecode to ensure that it initializes
rowsDecoded.
