tools: moveconfig: add --spl option to move options for SPL build

Prior to this commit, the tool could not move options guarded by
CONFIG_SPL_BUILD ifdef conditionals because they do not show up in
include/autoconf.mk.  This new option, if given, makes the tool
parse spl/include/autoconf.mk instead of include/autoconf.mk,
which is probably preferred behavior when moving options for SPL.

+   Look for moved config options in spl/include/autoconf.mk instead of
+   include/autoconf.mk.  This is useful for moving options for SPL build
+   because SPL related options (mostly prefixed with CONFIG_SPL_) are
+   sometimes blocked by CONFIG_SPL_BUILD ifdef conditionals.
