Introduce a boolean PCD that tells us whether TPM support is enabled in the build, and if it is, record the TPM base address in the existing routine that traverses the device tree in the platform PEIM. If a TPM is found, install the gOvmfTpmDiscoveredPpiGuid signalling PPI that will unlock the dispatch of OvmfPkg's Tcg2ConfigPei. If TPM2 support is enabled in the build but no TPM2 device is found, install the gPeiTpmInitializationDonePpiGuid PPI, which is normally installed by Tcg2ConfigPei if no TPM2 is found, but in our case Tcg2ConfigPei will never run so let's do it here instead.
