tools: mtk_image: split the code of generating NAND header into a new file

Browse source 
The predefined NAND headers take too much spaces in the mtk_image.c.
Moving them into a new file can significantly improve the readability of
both mtk_image.c and the new mtk_nand_headers.c.

This is a preparation for adding more NAND headers.
