03013084aa Fix SkATan2_255 fuzzer crash 
Test for degenerate values after computing the ratio, instead of
attempting to catch all tricky cases upfront.

Similar to https://skia-review.googlesource.com/8270, treat intervals
as closed at both extremities in the 4f gradient fallback impl also.

e659c7f36f [4fGradient] Relax interval checks 
We're currently considering intervals open at one extremity, in order to
ensure that a given value is always contained in a single interval.

This creates problems with synthetic clamp intervals [1, +inf), for
t == +inf (no interval can contain it).

Treat intervals as closed at both extremities instead.  This introduces
some ambiguitiy for overlapping values (contained in both adjacent
intervals), but solves the more serious problem above.
