Rename some signature-related identifiers

Rename some macros and functions related to signature which are
changing as part of the addition of psa_sign_message and
psa_verify_message.

 **Prerequisites to performing asymmetric signature operations:**
 * Initialize the library with a successful call to `psa_crypto_init()`.
 * Have a valid key with appropriate attributes set:
-    * Usage flag `PSA_KEY_USAGE_SIGN` to allow signing.
-    * Usage flag `PSA_KEY_USAGE_VERIFY` to allow signature verification.
+    * Usage flag `PSA_KEY_USAGE_SIGN_HASH` to allow signing.
+    * Usage flag `PSA_KEY_USAGE_VERIFY_HASH` to allow signature verification.
     * Algorithm set to the desired signature algorithm.
 
 This example shows how to sign a hash that has already been calculated:
