Łukasz Duda 2c0c3e84a3 [crypto] PSA API: support HKDF extraction with HMAC-SHA256 keys
The PSA platform now transparently handles HKDF operations when using
HMAC-SHA256 keys by exporting and re-importing them as volatile
HKDF-SHA256 keys. The export/import logic has been moved into the
platform layer. This change is required to support TREL and the PSA API
key usage restrictions.
