Convert CONFIG_SKIP_LOWLEVEL_INIT et al to Kconfig
This converts the following to Kconfig:
CONFIG_SKIP_LOWLEVEL_INIT
CONFIG_SKIP_LOWLEVEL_INIT_ONLY
In order to do this, we need to introduce SPL and TPL variants of these
options so that we can clearly disable these options only in SPL in some
cases, and both instances in other cases.
