Commodore 128: gfxram for the VDC 80 column #3

Noted with other computers that you have a gfxram field.

The Commodore 128 has additional RAM next to its main 128K RAM for the VDC 80 column mode video chip. Standard was 16k, some models (like the 128DCR) even have 64K. Which by the way also raises the question if the 128, 128D and 128DCR should have different entries because they have different specifications in price, hardware and gfx RAM.

Not sure how to include and ensure consistency, so did not create pull request.

The 128/128D/128DCR should probably be different files, but not sure how to notate the link between them. Will keep open for that reason, for now.
