  -----------
  pkcs11: Support for RSA PSS padding in verify

* Explicitly copies the mechanism parameters during a PKCS#11 `C_VerifyInit`
  and `C_DecryptInit` operation.
* Resolves issues where the calling application deallocates the `pParameter`
  pointer in the `CK_MECHANISM` struct between calls to `C_VerifyInit` and
  `C_Verify`, or between `C_DecryptInit` and `C_Decrypt`.
* These mech parameters are used in RSASSA-PSS and RSAES-OAEP, for example.
* This commit copies the same fix that was applied to `sc_pkcs11_sign_init` in
  commit e5707b545e5a2dc33b0ca52a8bf63f36f71b3d85 for supporting RSASSA-PSS.
