Add TPM2 support defined in trusted computing group.
TCG EFI Protocol Specification for TPM Family 2.0 Revision 1.0 Version 9 at http://www.trustedcomputinggroup.org/resources/tcg_efi_protocol_specification
TCG Physical Presence Interface Specification Version 1.30, Revision 00.52 at http://www.trustedcomputinggroup.org/resources/tcg_physical_presence_interface_specification
Add Tcg2XXX, similar file/directory as TrEEXXX. Old TrEE driver/library can be deprecated.
1) Add Tcg2Pei/Dxe/Smm driver to log event and provide services.
2) Add Dxe/Pei/SmmTcg2PhysicalPresenceLib to support TCG PP.
3) Update Tpm2 library to use TCG2 protocol instead of TrEE protocol.
Test Win8/Win10 with SecureBoot enabled, PCR7 shows bound.
