version: Store image size data in version struct
Store our image size (known at build time) in our version struct (now
renamed to image_data). This will allow us to more efficiently determine
the size of an image in a follow-up CL.
Note that compatibility is broken for old ROs that do not include this
CL.
BUG=chromium:577915
TEST=Verify on kevin + lars + lars_pd that stored image size matches
output of system_get_image_used() for both RO and RW images.
BRANCH=None
