feat(trp): test el3-rmm ide km interface
This patch introduces test functions to the Test Realm Payload (TRP)
for performing basic sanity checks on the RMM-EL3 IDE KM support added
to EL3.
The primary goal of this patch is to only to verify the basic
functionality and ensure the implemented functions return the
correct return values.
The test uses random values for the ecam address, rootport ID,
IDE stream info, keys, and IV values.
