Makes computeFastBounds not part of the public API, it's only accessible
to subclasses of SkPathEffect, GrStyle, and SkPaint. Subclasses can
invoke it other path effects using SkPathEffectPriv::ComputeFastBounds.
Changes the internal function to
bool computeFastBounds(SkRect* bounds) const;
Subclasses of SkPathEffect must implement this, and can choose to return
false when fast bounds aren't computable.
Provides implementations of computeFastBounds() for path effects
bundled with Skia.

Aside from sqrt() and normalize(), we now optimize all the intrinsics
which take a single argument as input, and return that argument with
each of its components permuted as output.
This CL also introduces a minor restriction--we no longer optimize
intrinsics which evaluate to inf or nan, such as `inversesqrt(-1)`.
These will be left in the source as-is.

SkSpan is a convenient type to use on API boundaries - callers can have
their collection in a stack-allocated array, or any contiguous container
(std::vector, etc). Those will all implicitly convert to SkSpan, making
call-sites easy to read/write.
Before making it part of Skia's public API, this CL removes parts of the
API that aren't present in std::span -- when Skia moves to C++20, this
should allow us to use std::span instead, and remove SkSpan entirely.
The most disruptive change is the removal of `int count()`. That's
replaced by a new free function `SkCount` that works on any container,
and incorporates the overflow check from SkTo<int>.

It took a few "independent" changes in order to get the linked fuzzer
bugs to pass without failing. Leaving any out triggered an issue :/
1. I changed nearly_flat to be <= epsilon, since if it's == epsilon and
we split the edge, then the new coordinates would have
difference < epsilon.
2. I updated double_to_clamped_scalar to also snap very small values to
0 (right now 16 * float epsilon).
3. double_to_clamped_scalar is now used to clean up the computed
intersection of two edges, and is used to process all initial
vertices (in case the curve evaluation generates lots of denormals
etc.)
4. I updated the use of nearly_flat in checkForIntersection to report
no intersection if both lines are nearly_flat. The comments suggest
nearly_flat means you can't split along that line since the new
coord is incalculable. So if both lines are flat, it's a really
tough numerical scenario and I just punt.
Then I made a few other changes for the fuzzer and debugging:
1. Added more logging messages and updated the code so that it compiles
correctly if TRIANGULATOR_LOGGING is defined.
2. I was also getting asserts in the fuzzer because the vertex
allocator expects the vertex buffer to be detached by the path
renderer before its destroyed, so I just have the fuzzer detach and
discard it. Running locally, the fuzzer test cases from the two
linked bugs pass successfully without oom'ing or timing out.
