In OEMCrypto v14, SelectKey can also return KEY_NOT_LOADED if the key
id is not found. This was added to help with entitlement licenses.
However, SelectKey in crypto session converts this to an unknown
error.
In this CL we change that to a NO_CONTENT_KEY_3 error. This is
probably only important because the generic crypto tests expect
NO_CONTENT_KEY_3 when we try to use an undefined key.
Test: existing unit tests pass, and some future unit tests pass.
Bug: 72354901 Turn on generic crypto tests
