MdeModulePkg: Remove Ip4ConfigDxe and related guid definition

Ip4ConfigDxe driver is deprecated in UEFI 2.5, so we will not support original Ip4Config Protocol, 
which is replace by Ip4Config2 Protocol integrated in Ip4Dxe driver(git commit 1f6729ff (SVN r17853)).

Dependent network drivers, libraries and applications have been migrated to (or extended to) the new protocol version.
For example:
git 7c25b7ea (SVN r17869): ping & ifconfig
git 00a6ad1b (SVN r17870): UefiHandleParsingLib
git 6c5c70d6 (SVN r17873): DxeNetLib
git 39561686 (SVN r17874): IpSecDxe
git c581e503 (SVN r17875): EfiSocketLib

This patch is based on related packages(MdeModulePkg, Nt32Pkg,  ArmPlatformPkg, ArmVirtPkg, EmulatorPkg, OvmfPkg, Vlv2TbltDevicePkg) clean-up work finished.
