[edk2-devel] [Patch V4 1/8] MdePkg: Move CpuPageTableLib definition to MdePkg

[duntan]

Move CpuPageTableLib definition from UefiCpuPkg to MdePkg. The
lib instance still remains in UefiCpuPkg. Move CpuPageTableLib
definition to a common location can avoid the case that
MdeModulePkg need to depend on UefiCpuPkg since DxeIpl module
in MdeModulePkg needs to consume CpuPageTableLib.
