Revert "align the different implementations of 1/x"

This reverts commit 828987893bff5008fcbd15e343485b708d673b33.

Reason for revert: breaks Waymo

Original change's description:
> align the different implementations of 1/x
> Before this CL, the current rcp (1/x) calculation has enough precision
> for color calculations, but not enough for positional calculations.
> Introduce a new reciprocal called recip that has more precision for
> positions. On Intel, this requires the addition of a Newton-Raphson
> iterations, and ARM requires two NR iterations.
> Bug = skia:12453
