feat(esp8266): add system version

Browse Source 
Bootloader can get the version of application for specific section,
and then check if some features are supported.

Developers can use the macro "ESP_IDF_VERSION" to limite some function like following:

include "esp_idf_version.h"

if ESP_IDF_VERSION >= ESP_IDF_VERSION_VAL(3, 4, 0) && ESP_IDF_VERSION < ESP_IDF_VERSION_VAL(4, 0, 0) // 3.4 <= ver < 4.0
    do_xxx_process();
endif
