OvmfPkg: create Tcg12ConfigPei.inf

Split Tcg2ConfigPei.inf into two variants: Tcg12ConfigPei.inf with
TPM 1.2 support included and Tcg2ConfigPei.inf supporting TPM 2.0 only.
This allows x86 builds to choose whenever TPM 1.2 support should be
included or not by picking the one or the other inf file.

Switch x86 builds to Tcg12ConfigPei.inf, so they continue to
have TPM 1.2 support.

No functional change.
