v1.3.0 to add support to LAN8720

### Releases v1.3.0

1. Add support to **LAN8720** Ethernet for many **STM32F4** (F407xx, NUCLEO_F429ZI) and **STM32F7** (DISCO_F746NG, NUCLEO_F746ZG, NUCLEO_F756ZG) boards.
2. Add LAN8720 examples
3. Add Packages' Patches for STM32 to use LAN8720 with STM32Ethernet and LwIP libraries
4. Reduce compiled code size.
