The test case was producing a stack trace of sequential path transforms.
While each individual call would check to see if the path is too big
and return, the resulting path kept getting continually bigger as we
transformed it again and then popped the stack. This CL changes it to
skip the transform op if the returned path is already too big.

Large paths can lead to large processing times for path effects and
hence timeouts.
Also re-enables ShrinkToFit test until that code is finally removed,
but using the PathPriv interface instead.

Step one is to make it private -- only skottie needs it at the moment
Stpe two is to modify pathops to use builders, and then we can likely
remove it shrinkToFit entirely (since builder.snapshot() is already snug).

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.

Chrome added a public method to validate SkPathRef,
but always called it when validating SkPath. We did too.
Remove the SkPathRef entry point, validate SkPathRef
when validating SkPath, and remove Skia's callers.
(Chrome has already been fixed.)

Doesn't look like we need to distinguish these if we just
write them as the simple
1) load the right number of bytes
2) clamp to [min,max]
This makes enum fuzzing independent of its underlying type, and may make
it easier to see the mapping from fuzzed byte stream to
nextRange()/nextEnum() values.

This CL renames FuzzPath() to FuzzNicePath() to remind us that it's
meant to create paths that a user could reasonably want to create
in good faith, to pass to Skia via its API, etc.
Then, add fuzz_nice_rect(), and have FuzzNicePath() use that to create
its rectangles and use FuzzNiceMatrix() to create its matrices, just
like we already use FuzzNiceRRect() to create rounded rectangles and
FuzzNicePath() itself to create sub-paths.
Using fuzz_nice_rect() should be the fix for the attached bug.
Using FuzzNiceMatrix() is by analogy, more preemptive.
While we're at it, rename BuildPath to FuzzEvilPath, so the contrast
with FuzzNicePath is more clear.
Update the assertions that we create a valid path in FuzzNicePath()
to tell us where things went wrong if they do.

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.
