trailingThumbnail for Material.Chip

[dpinn]

The Material.Chip module currently has a leadingThumbnail, but lacks a trailingThumbnail. I'd like there to be a trailingThumbnail function so that my app can respond to clicks on the Remove icon.

As a workaround, I'm not using the trailingIcon property and instead attach an IconButton to the end of the text inside the chip.
