libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig. When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.

Add new CONFIG(XXX) macro to replace IS_ENABLED(CONFIG_XXX) The IS_ENABLED() macro is pretty long and unwieldy for something so widely used, and often forces line breaks just for checking two Kconfigs in a row. Let's replace it with something that takes up less space to make our code more readable.
