Specialize Sk2d for ARM64
The implementation is nearly identical to Sk2f, with these changes:
- float32x2_t -> float64x2_t
- vfoo -> vfooq
- one extra Newton's method step in sqrt().
Also, generally fix NEON detection to be defined(SK_ARM_HAS_NEON).
SK_ARM_HAS_NEON is not being set on ARM64 bots right now (nor does the compiler
seem to set __ARM_NEON__), so this CL fixes everything up.
