OvmfPkg/Tcg2ConfigPei: factor out InternalTpm12Detect()

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.
