According to PSA specification in case of `PSA_KEY_TYPE_ECC_KEY_PAIR`
function `psa_import_key` takes private key from key pair as argument.
This commit adds extraction of Private key from ECDSA key pair.
Also removes not needed `otPlatCryptoEcdsaGetPublicKey`.

Remove two workarounds in OpenThread's PSA crypto backend
that were required when Zephyr used pre-1.5 TF-M version:
1. psa_open_key() is no longer needed to reference
a persistent key
2. psa_cipher_encrypt() can be used to simplify AES
encryption

In OpenThread, Settings are initialized after KeyManager by default.
If device uses PSA with emulated TFM, Settings have to be initialized
at the end of otPlatCryptoInit(), to be available before storing
Network Key.

The psa_generate_random function requires the psa_crypto_init call
before the usage. This can be ensured by calling the psa_crypto_init
in otPlatCryptoRandomInitfunction.
