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.

37c0f7183e Add guidance for oss-fuzzer for new path version
This only changes it for the oss-fuzz executable
which allows our normal fuzz executable to repro
on older versions, if needed.

This CL also accompanies additions to the corpus
of a bunch of v4 paths.

f034d11859 Break some fuzzer targets out so oss-fuzz can use them
FuzzImageFilterDeserialize is already being used in oss-fuzz
but the target lived there and not here.  This moves it here.

Then we can turn on:
 - FuzzPathDeserialize
 - FuzzTextBlobDeserialize
