feat(esp8266): supports "make size" and its family function
1. support "make size", "make size-files", "make size-components" and "make size-symbols" 2. add esp-idf style link file including "esp8266.ld" and "esp8266.project.ld.in" 3. add link advaced generation file to components of esp8266 and spi_flash
