TEST-ONLY: ctc module on cavs2.5-001-drop-stable

[johnylin76]

For testing purposes, it backports CTC module from main to cavs2.5-001-drop-stable

To make the FW build with CTC library:

1. patch commits onto your local cavs2.5-001-drop-stable branch
2. put libgoogle_ctc_audio_processing.a to third_party/lib/
3. put libc++.a and libc++abi.a to third_party/lib/
4. set xtensa env arguments

export XTENSA_TOOLS_ROOT=$(YOUR/XCC/ROOT)
export XTENSAD_LICENSE_FILE=$(YOUR/XCC/LICENSE/DAT)

5. make build by command:

./scripts/xtensa-build-all.sh -o tigerlake_chrome_ctc tgl
