libpayload: Reintroduce CONFIG_LP_CHROMEOS to set suitable defaults
Chrome OS builds always have some inherent differences to "standard" libpayload configurations: they don't want to use curses or things like storage drivers, they always use the coreboot framebuffer and USB, etc. This patch reintroduces CONFIG_LP_CHROMEOS as an option that only affects Kconfig defaults. This allows Chrome OS builds to select most of what they need in one go and reduces board-specific .config files to only the options that are really specific to that board. Also restricts the 8250_SERIAL_CONSOLE Kconfig to only default to yes on x86 boards, which probably makes sense for all of libpayload (some but far from all ARM boards use 8250-compatible UARTs, and we should probably not default a platform option unless it's going to be correct with very high probability). BRANCH=None BUG=None TEST=Built and booted Jerry and Oak.
