MdeModulePkg: IP4 should re-initiate a DHCP if it detects network reconnection
v2:
* Update the MediaPresent detect declaring.
IP4 driver should re-initiate a DHCP if it detects that there is a network.
To fix this issue, we can implement the DHCP re-initiate policy while the media
change detected. The Ip4 driver should set a timer to signal the Ip4 to run the
DHCP configuration again(D.O.R.A). IP4 driver should free old IP address related
resource, then initiate a DHCP process to acquire new IP.
