pki: Remove unused function pki_signature_verify()

This removes unused function pki_signature_verify()
from pki_{crypto, mbedcrypto, gcrypt}.  The function was also removed
from include/libssh/pki_priv.h.  The function ssh_pki_signature_verify()
was changed to receive a const unsigned char *input.

All tests calling pki_signature_verify() were changed to call
ssh_pki_signature_verify() instead.
