SecurityPkg/Tpm12CommandLib: Add TPM 1.2 commands used by TCG modules
Add the following APIs that are required by TcgPei and/or TcgDxe to the Tpm12CommandLib instance: Tpm12Extend() Tpm12PhysicalPresence() Tpm12ContinueSelfTest() Tpm12GetCapabilityFlagPermanent() Tpm12GetCapabilityFlagVolatile() Cc: Chao Zhang <chao.b.zhang@intel.com> Cc: Jiewen Yao <jiewen.yao@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Michael Kinney <michael.d.kinney@intel.com> Reviewed-by: Chao Zhang <chao.b.zhang@intel.com> Reviewed-by: Jiewen Yao <jiewen.yao@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@19727 6f19259b-4bc3-4df7-8a09-765794883524
