ta: pkcs11: Don't load objects that don't match the search during find

Don't load all persistent object attributes in find_objects_init().
Instead, temporary load object attributes and release them if not matching
the current search.

Move object attribute loading from token_obj_matches_ref() to
load_persistent_object_attributes() and introduce counterpart
release_persistent_object_attributes().

Changes attributes_match_reference() to always return true when reference
is empty (match all case).

Remove token_obj_matches_ref() since attributes_match_reference() can be
called straight from load_persistent_object_attributes().

The logic to deal with the private objects was missing in the
C_Logout() implementation.
PKCS#11 specification states that :
When C_Logout successfully executes, any of the application’s
handles to private objects should become invalid (even if a user
is later logged back into the token, those handles remain invalid).
In addition, all private session objects from sessions belonging
to the application should also be destroyed.

In addition, also release any ongoing cryptographic or
object-finding operations that may be associated with the session
while logging out.

- only public objects can be destroyed unless the normal user is

- Certain objects may not be destroyed. Calling C_DestroyObject on
such objects will result in the CKR_ACTION_PROHIBITED error code.
An application can consult the object's CKA_DESTROYABLE
