BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4123 VmgExitLib once was designed to provide interfaces to support #VC handler and issue VMGEXIT instruction. After TDVF (enable TDX feature in OVMF) is introduced, this library is updated to support #VE as well. Now the name of VmgExitLib cannot reflect what the lib does. This patch renames VmgExitLib to CcExitLib (Cc means Confidential Computing). This is a simple renaming and there is no logic changes. After renaming all the VmgExitLib related codes are updated with CcExitLib. These changes are in OvmfPkg/UefiCpuPkg/UefiPayloadPkg.
