crypto: remove POINT_CONVERSION_HYBRID from documentation.

Compressed points are already rare and, as far as I know, nobody has used
the 'hybrid' format anywhere, ever. It's prohibited in X.509
certificates too[1].

This change removes mentions of it from the documentation in the
interests of trying to pare-down the complexity of cryptography.
