PSA_EXPORT_KEY_PAIR_MAX_SIZE macro

Sufficient buffer size for exporting any asymmetric key pair. This macro expands to a compile-time constant integer. This value is a sufficient buffer size when calling psa_export_key() to export any asymmetric key pair, regardless of the exact key type and key size. See also #PSA_EXPORT_KEY_OUTPUT_SIZE(\p key_type, \p key_bits).
