make: add size calculations
Room remaining in flash is an ever important property of many EC
images. This patch adds a makefile rule with will calculate how much
free room is left in the RW partition with the current image.
The calculation uses two variables set by the linker: 'FLASH' which
shows how much room is allocated to the image and '__image_size' which
shows how much room is actually taken. The difference is how much room
is still available.
Wnen building with V=0, size is not reported.

$ rm -rf build/cr50/
$ make BOARD=cr50 CR50_DEV=1 -j
*** 4488 bytes still available in flash on cr50 ****
