Angus Gratton 077469c823 partition_table: Support same fallback logic as bootloader for default boot partition
Generates correct "make flash" command even when partition table has no factory partition.

Also adds unit tests for parttool.py

# Partition table
#
# The partition table is not a real component that gets linked into
# the project. Instead, it is a standalone project to generate
# the partition table binary as part of the build process. This
# binary is then added to the list of files for esptool.py to flash.
