vga: Start cutting out non-32bpp conversion support 

Nowadays, we either share a surface with the host, or we create
a 32bpp ARGB console surface.

So we only need to draw/convert to 32bpp, enabling us to remove
all but one instance of vga_template.h inclusion (to be further
cleaned up), rgb_to_pixel_* etc...
