fix(lib/psa): update measured boot handle

When the measured boot service was upstreamed to TF-M, its static
handle was reallocated into the user partitions range. This change
updates the static handle here to make the service accessible.

Also removes the SIDs and Versions, since they are unused when a
service is accessed through a stateless handle, which encodes both
service ID and version. The attestation and measured boot services
only support access through their handles.
