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-set renames VmgExitLib to CcExitLib (Cc means Confidential
Computing). This is simple renaming and there is no logic changes. Then
APIs defined in CcExitLib.h are added with a CcExit prefix. This is to
make the name more meaningful.

Code: https://github.com/mxu9/edk2/tree/CcExitLib.v4

v4 changes:
 - The previous versions of the patch-set are to first duplicate a new
   CcExitLib then delete the old VmgExitLib. According to this comments
   https://edk2.groups.io/g/devel/message/96019 it suggests renaming in
   a single patch is better.
 - Lib APIs are added with CcExit prefix, not CcExitLib prefix.

v3 changes:
 - Rename CcExitHandleVc / CcExitHandleVe to
   CcExitLibHandleVc / CcExitLibHandleVe to make the nameing consistent.
 - Update the CcExitLib to merge the patch eff44c008d99
  (OvmfPkg/VmgExitLig: HALT on #VE when access to private memory).
 
v2 changes:
 - Patch #3 is added to import CcExitLib in OvmfPkg's *.dsc. This is to
   prevent the building from being broken in the following patches.
