Add OS2ECP benchmark.
Turns out decompressing a point is ~50x slower than checking (x,y) is on the curve. Update relnote accordingly.

* Add support for the TLS Supported Point Formats Extension from RFC 4492. Adds
TLS::Policy::use_ecc_point_compression policy option. If supported on both
- sides, ECC points can be sent in compressed format, which both saves a few
- bytes on the wire and is an inexpensive way of avoiding invalid curve attacks.
- For uncompressed points Botan already checks that the point is on the curve so
- invalid curve attacks are not possible in either situation, but the point
- decompression will typically be cheaper than verifying the point is on the
- curve. (GH #645)
