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.
