[skottie] Fix bluge effect sampling resolution
The bulge effect samples into a picture shader, and after recent changes
in shader chain handling of transforms, we started over-allocating the
picture tile.
To work around, move the normalization logic to sksl so that it doesn't
interfere with tile sizing.
