lib: Add Kconfig to toggle boot state debugging

Add the DEBUG_BOOT_STATE Kconfig value to enable boot state debugging.
Update include/bootstate.h and lib/hardwaremain.c to honor this value.
Add a dashed line which displays between the states.

Testing on Galileo:
* select DEBUG_BOOT_STATE in mainboard/intel/galileo/Kconfig
* Build and run on Galileo
