Passing CK_P11PROV_IMPORTED_HANDLE while creating mock public key

This commit adds CK_P11PROV_IMPORTED_HANDLE argument while creating mock
public key session object.

Before this patch, when we run TLS1.3 connection, below issue was reported
by openssl:-
tls_parse_ctos_key_share:unable to find ecdh
parameters:ssl/statem/extensions_srvr.c:684

It is because of returning CK_INVALID_HANDLE instead of obj->handle.
