kconfig: refactor scanning and parsing "option" properties
For the keywords "modules", "defconfig_list", and "allnoconfig_y", the lexer should pass specific tokens instead of generic T_WORD. This simplifies both the lexer and the parser. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
