OvmfPkg: Update code to be more C11 compliant by using __func__
...
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

OvmfPkg: Add INVD case in #VE handler
...
According to the Intel GHCI specification document section 2.4.1, the
goal for instructions that do not have a corresponding TDCALL is for the
handler to treat the instruction as a NOP.
INVD does not have a corresponding TDCALL. This patch makes the #VE
handler treat INVD as a NOP.

OvmfPkg/UefiCpuPkg/UefiPayloadPkg: Rename VmgExitLib to CcExitLib
...
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.
