[Task][SBSA]: Consider Testing with TPM Functionality

[makubacki]

Feature Overview

Since Patina substitutes the DXE Core implementation today, it impacts a number of global services and data stores related to industry standard code like TCG related libraries and drivers. These rely on TPL, protocols, HOBs, etc. In the future it is possible TPM related drivers will be written in Rust within Patina.

This issue tracks enabling testing with TPM enabled. Such as in nightly regression testing.

---

Note: TPM support is easier to enable in Q35 than SBSA as the upstream code has built-in support. Therefore, TPM enabling in patina-qemu is broken into two separate issues for SBSA (this one) and Q35.

Been validating various approaches, including fTPM solution from the edk2, customized QEMU, and switching to another platform. At this point, the switch to ARM-Virt machine is the most effective way forward.

Compared to SBSA, the TFA is better maintained and we will not need to carry those custom patches, the hafnium has an existing build configuration that is sufficient for our usage. The TPM device can be added during QEMU launching time just like Q35.

So we will be switching over to Arm-Virt machine type shortly. Then we will onboard the TPM test.
