Revert "global: Remove CONFIG_SYS_EXTRA_OPTIONS support"

Unfortunately, we require additional logic to buildman to support this
removal and still use SYS_SOC, etc, for build targets.

This reverts commit eeec00072d.

The old configuration infrastructure (= mkconfig + boards.cfg)
provided the extra options field. If you have something like
"HAS_BAR,BAZ=64", the optional options
#define CONFIG_HAS
#define CONFIG_BAZ 64
will be defined in include/config.h.
This option was prepared for the smooth migration from the old
configuration to Kconfig. Since this option will be removed sometime,
new boards should not use this option.

----
- The option field of boards.cfg, which was used for the pre-Kconfig
configuration, moved to CONFIG_SYS_EXTRA_OPTIONS verbatim now.
Board maintainers are expected to implement proper Kconfig options
and switch over to them. Eventually CONFIG_SYS_EXTRA_OPTIONS will go away.
CONFIG_SYS_EXTRA_OPTIONS should not be used for new boards.
- In the pre-Kconfig, a single board had multiple entries in the boards.cfg
file with differences in the option fields. The corresponding defconfig
files were auto-generated when switching to Kconfig. Now we have too many
