Kconfig: Unify power-after-failure options
The newest and most useful incarnation was hiding in soc/intel/common/.
We move it into the Mainboard menu and extend it with various flags to
be selected to control the default and which options are visible. Also
add a new `int` config MAINBOARD_POWER_FAILURE_STATE that moves the
boolean to int conversion into Kconfig:
0 - S5
1 - S0
2 - previous state
This patch focuses on the Kconfig code. The C code could be unified as
well, e.g. starting with a common enum and safe wrapper around the
get_option() call.
TEST=Did what-jenkins-does with and without this commit and compared
binaries. Nothing changed for the default configurations.
