image: add RGBA64Image interface
The new RGBA64At method is equivalent to the existing At method (and the
new SetRGBA64 method is equivalent to the existing Set method in the
image/draw package), but they can avoid allocations from converting
concrete color types to the color.Color interface type.
Also update api/go1.17.txt and doc/go1.17.html
Fixes #44808
