RFR: 8351108: ImageIO.write(..) fails with exception when writing JPEG with IndexColorModel [v3]

[Jeremy Wood]

> Previously ImageTypeSpecifier treated all TYPE_BYTE_INDEXED as if they were opaque.
> 
> In this ticket's case: an ImageWriter received the wrong ImageTypeSpecifier and mistakenly indicated it *could* support a BufferedImage. But when the actual BufferedImage arrived (which was translucent), the ImageWriter threw an exception.
> 
> Instead:
> Now the ImageTypeSpecifier accurately describes the given BufferedImage.
