Remove RSA_SIGN and RSA_ENCRYPT as they are deprecated 

This change removes two mechanisms that are deprecated in RFC 4880. The
spec explicitly mentions that "RSA Encrypt-Only (2) and RSA Sign-Only
are deprecated and SHOULD NOT be generated" [0].

The remaining RSA_GENERAL key type was renamed to just RSA for ease of
use for developers.
