global_platform/euicc: Implement obtaining SCP keys from CardKeyProvider

Browse Source 
Now that CardKeyProvider is capable of storing key materials
transport-key-encrypted, we can use this functionality to look up the
SCP02 / SCP03 key material for a given security domain.

This patch implements this for the ISD-R and ECASD using a look-up by
EID inside the CSV.
