[nrf noup] boot: zephyr: deprecate non-PSA ECDSA/Ed25519 implementations

These are not implementations that we want to support, so deprecate
them for future removal.

The current RSA implementation must be deprecated and removed as well
but not deprecating it yet because it's the only RSA implementation
option at the moment. We can deprecate and remove it once we have a
proper PSA alternative.
