#2325: [raster]: ST_SetBandNoDataValue support setting multiple bands

I find myself doing stuff like this:
st_setbandnodatavalue(st_setbandnodatavalue(rast,1,0),2,0) etc.
I feel like I've mentioned this before so this may be a dupe though I
can't find it.
Not only is it slow because of the memcopy commands, but its pretty ugly
to look at.
ideally:
ST_SetBandNoDataValue(rast,'{1,2,3}'::int[],'{0,0,0}'::int[] );
would have been even nicer if the rast,nodatavalue version just set all
the bands to whatever value is passed in, but I guess that would be
changing the semantics so maybe a nono - though we did it already with
ST_Union :)
