RFR: 8376510: Raster.createBandedRaster(int, int, int, int, int[], int[], Point) does not check for negative scanlineStride

[Phil Race]

We specify that scanlineStride < 0 will throw IAE, but it was not checked up front in all cases, so sometimes would be IAE and sometimes NegativeArrayIndexException.
Add an explicit check.
