MdeModulePkg: Change the default IPv4 config policy

Browse Source 
Git version '3d0a49ad' commit provided a scenario to resolve the
performance issue for IPv4, but it's not workable for IPv6. To
avoid IPv4 and IPv6 inconsistency, we decided to revert that version
fix.

If so, the default policy for Ip4Config2 is Ip4Config2PolicyDhcp,
which results in all NIC ports attempting DHCP. So, this patch is
used to changes the the default IPv4 config policy to
Ip4Config2PolicyStatic and also defer the SetData operation after
Ip4Config2Protocol installed. This update let the other platform
drivers have chance to change the default config data by consume
Ip4Config2Protocol.
