Laszlo Ersek 9f9bf82209 OvmfPkg/IntelTdx: auto-gen & fix SEC ProcessLibraryConstructorList() decl 
<Library/PeimEntryPoint.h> declares a bogus
ProcessLibraryConstructorList() for IntelTdx's SEC module. Rely on AutoGen
for (properly) declaring ProcessLibraryConstructorList(). Update the call.

Build-tested with:

  build -a X64 -b DEBUG -m OvmfPkg/IntelTdx/Sec/SecMain.inf \
    -p OvmfPkg/IntelTdx/IntelTdxX64.dsc -t GCC5

Yu Pu cd81e8e030 OvmfPkg: Remove UefiCpuLib from module INFs. 
Because UefiCpuPkg/UefiCpuLib is merged to MdePkg/CpuLib, remove the
dependency of UefiCpuLib.

Zhiguang Liu bf0c14a562 OvmfPkg: Add CpuLib to module INFs that depend on UefiCpuLib. 
There are two libraries: MdePkg/CpuLib and UefiCpuPkg/UefiCpuLib and
UefiCpuPkg/UefiCpuLib will be merged to MdePkg/CpuLib. To avoid build
failure, add CpuLib dependency to all modules that depend on UefiCpuLib.

Min Xu 76fda1def3 OvmfPkg: Call CcProbe in SecMain.c instead of TsIsEnabled 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902

TdIsEnabled() uses the CPUID instruction. At this point, exception
handling is not established and a CPUID instruction will generate
a #VC and cause the booting guest to crash.

CcProbe() checks Ovmf work area to return the guest type. So call
of CcProbe() instead of TdIsEnabled() to fix the above issue.

Min Xu 1f29de4d20 OvmfPkg/IntelTdx: Add Sec to bring up both Legacy and Tdx guest 
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

OvmfPkg/IntelTdx/Sec is a simplied version of OvmfPkg/Sec. There
are below differences between these 2 Sec
 - IntelTdx/Sec only supports Legacy guest and Tdx guest in X64.
 - IntelTdx/Sec calls PeilessStartup () to jump from SEC to DXE directly.
 - IntelTdx/Sec uses MemoryAllocationLib / HobLib / PrePiLib in
   EmbeddedPkg.
