OvmfPkg/IntelTdx: Measure TdHob and Configuration FV in SecMain
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243
TdHob and Configuration FV (Cfv) are external inputs from VMM. From the
security perspective, they should be measured before they're consumed.
This patch measures TdHob and Cfv and stores the measurement values in
WorkArea.
After TdHob and Configuration FV (Cfv) are measured in SecMain, the
same measurements in PeilessStartupLib are deleted.

OvmfPkg: Refactor ProcessHobList
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243
ProcessHobList once was implemented in PlatformInitLib and it walks thru
TdHob list and accept un-accepted memories.
This patch moves the codes to SecTdxHelperLib and rename ProcessHobList
as TdxHelperProcessTdHob
After TdxHelperProcessTdHob is introduced, below changes are applied:
- Call TdxHelperProcessTdHob instead of ProcessHobList in SecMain.c
(in both OvmfPkgX64/Sec and IntelTdx/Sec).
- Delete the duplicated codes in PlatformInitLib

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.

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.
