Implement computeFastBounds for PathEffects

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.
