Add TPM Replay FW CFG Input Channel library instance

[makubacki]

Description

Adds a new library instance for QEMU platforms that allows a TPM
Replay event log to optionally be passed from the QEMU command
line.

See https://github.com/microsoft/mu_plus/tree/HEAD/TpmTestingPkg/TpmReplayPei#input-channel-fw_cfg
for more information about passing a TPM Replay log through the
FW CFG interface.

For reference, this readme has additional TPM Replay information:

How This Was Tested

• Passed FW CFG TPM event log through QemuQ35Pkg
• Verified library integrated without a log being passed uses
  lower priority input channels as expected

Integration Instructions

N/A - The new input channel library instance for TPM Replay is integrated
in this change.

Waiting on microsoft/mu_plus#352 to complete and then I'll update the Common/MU submodule a final time before completing this PR.
