MdeModulePkg/ArmFfaLib: Add HobLib to StMm instances

makubacki · mergify[bot] · commit 2558af552d73 · 2025-09-12T07:31:53.000Z
ArmFfaCommon.c is built by both ArmFfaStandaloneMmCoreLib and
ArmFfaStandaloneMmLib. It links against HobLiib APIs such as
`GetFirstHob()`. Right now, the symbols fail to link:

```
lld-link: error: undefined symbol: GetFirstHob
          ArmFfaStandaloneMmCoreLib.lib(ArmFfaCommon.obj)
```
