build_library: write partition variables to a json file

Moving chromeos_startup to cpp and we still need access to the
partition variables loaded by write_gpt.sh. Generating a json
file to contain these variables will allow us to access them
from the cpp files.

BUG=chromium:1048728
TEST=build_image --board=hatch, json file exists on device
Checked /usr/sbin/write_gpt.sh sections load_base_vars()
and load_partition_vars() are correct
