Add Perlin noise stage to Raster Pipeline.
This replaces our legacy shadeSpan-based Perlin noise implementation
with a Raster Pipeline-based equivalent. The new version works in
local space, so it can honor the canvas transform; previously,
rotation was broken. It is over 3x faster than the original scalar
implementation on an M1 Max.
The relevant Chrome tests have already been disabled in preparation
for a rebaseline.
