OvmfPkg: Support Tdx measurement in OvmfPkgX64
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243
This patch enables Tdx measurement in OvmfPkgX64 with below changes:
1) CC_MEASUREMENT_ENABLE is introduced in OvmfPkgX64.dsc. This flag
indicates if Intel TDX measurement is enabled in OvmfPkgX64. Its
default value is FALSE.
2) Include TdTcg2Dxe in OvmfPkgX64 so that CC_MEASUREMENT_PROTOCOL
is installed in a Td-guest. TdTcg2Dxe is controlled by
TDX_MEASUREMENT_ENABLE because it is only valid when Intel TDX
measurement is enabled.
3) OvmfTpmLibs.dsc.inc and OvmfTpmSecurityStub.dsc.inc are updated
because DxeTpm2MeasureBootLib.inf and DxeTpmMeasurementLib.inf
should be included to support CC_MEASUREMENT_PROTOCOL.
