Move the calls to the Tpm12RequestUseTpm() and Tpm12SubmitCommand() Tpm12DeviceLib functions to a separate C file, so that we can override these actions in a subsequent patch. This code movement requires moving the TPM_RSP_GET_TICKS / TestTpm12() helper structure / function too. While at it, give the TestTpm12() function @retval / @return documentation, plus wrap an overlong line in it. Functionally, this patch is a no-op.
