test: dm: Add test for ECDSA UCLASS support
This test verifies that ECDSA_UCLASS is implemented, and that
ecdsa_verify() works as expected. The definition of "expected" is
"does not find a device, and returns -ENODEV".
The lack of a hardware-independent ECDSA implementation prevents us
from having one in the sandbox, for now.
