core: add common implementation for console_putc() and console_flush()

Since most platforms now use the same console_putc() and
console_flush(), move them to core/kernel/console.c. Make them __weak
so that platforms may still provide their own.
The common code expects the platforms to initialize whatever serial
device from console_init() and call register_console().
