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

0c60708737 add utility for caching char2glyph
Try: out/release/nanobench --match _charToGlyph

Pseudo plan to use this:
- attach to whatever typeface backends need it (probably just freetype)
- have a purge/limiting scheme (e.g. only cache N entries)
- if we care, make the search fancier (e.g. binary, slope, etc.)

2416f968a6 Add 2 fuzz targets for image decoding (oss-fuzz)
This also adds in a few small guards to prevent libfuzzer from frequently
running out of memory when an image claims to have billions of pixels.

8dc8dbc821 begin cleanup of malloc porting layer
1. Merge some of the allocators into sk_malloc_flags by redefining a flag to mean zero-init
2. Add more private helpers to simplify our call-sites (and handle some overflow mul checks)
3. The 2-param helpers rely on the saturating SkSafeMath::Mul to pass max_size_t as the request,
which should always fail.

7ca9a74fef Remove uses of sk_throw.
The sk_throw macro is now an alias to SK_ABORT, but is often used when
other macros better describe the situation. This change replaces
sk_throw with SK_ABORT or SkASSERT_RELEASE as appropriate.
