SecurityPkg: Tcg2Smm: Separate Tcg2Smm into 2 modules

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3169

This change separated the original Tcg2Smm module into 2 drivers: the
SMM driver that registers callback for physical presence and memory
clear; the Tcg2Acpi driver that patches and publishes ACPI table for
runtime use.

Tcg2Smm introduced an SMI root handler to allow Tcg2Acpi to communicate
the NVS region used by Tpm.asl and exchange the registered SwSmiValue.

Lastly, Tcg2Smm driver will publish gTcg2MmSwSmiRegisteredGuid at the end
of entrypoint to ensure Tcg2Acpi to load after Tcg2Smm is ready to
communicate.

+#  This driver implements TPM 2.0 definition block in ACPI table and
+#  populates registered SMI callback functions for Tcg2 physical presence
+#  and MemoryClear to handle the requests for ACPI method. It needs to be
+#  used together with Tcg2 MM drivers to exchange information on registered
+#  SwSmiValue and allocated NVS region address.
+#
+#  Caution: This module requires additional review when modified.
+#  This driver will have external input - variable and ACPINvs data in SMM mode.
+#  This external input must be validated carefully to avoid security issue.
