This patch series enable Firmware Handoff [1] CI tests on qemu_arm64 by:
1. fetch MbedTLS (v3.6), OP-TEE (v4.7.0) and TF-A (v2.13.0);
2. build bl1 and fip with both Firmware Handoff and Measured Boot
   enabled;
3. pytest to validate the Firmware Handoff feature via bloblist by
   checking the existence of expected FDT nodes and TPM events generated
   and handed over from TF-A/OP-TEE.
