Add TPM2 definition in trusted computing group. 

1) TCG Physical Presence Interface Specification 1.30 at http://www.trustedcomputinggroup.org/resources/tcg_physical_presence_interface_specification
2) TCG EFI Protocol Specification for TPM 2.0 at http://www.trustedcomputinggroup.org/resources/tcg_efi_protocol_specification
3) Update TPM2.0 header file to include Hash Algo definition.
4) Update UEFI TCG platform header file to include more TCG event structure.

Test Win8/Win10 with secure boot enabled, PCR7 shows bound.
