reverted naming to premul alpha (no T)

Initially 3d had premulT alpha as a keyword.
Since Canvas item uses mixed premul and premult as keywords,
3D is changed as well to keep consistency with 2D.
Unfortunately this keeps inconsistency with the internal ENUM.

-			The color of the object is added to the background and the alpha channel is used to mask out the background. This is effectively a hybrid of the blend mix and add modes, useful for FX like fire where you want the flame to add but the smoke to mix. By default, this works with unshaded materials using premultiplied textures. For shaded materials, use the PREMUL_ALPHA_FACTOR built-in so that lighting can be modulated as well.
