Revamp test coverage for invalid key shares

We weren't testing all kinds of load-bearing checks in the TLS stack
around key shares. Fix this.

- Rework runner's KEM abstraction so that all the operations can get at
  config. That saves a lot of manual plumbing.

- Make the bad ECDH point something not on the curve. That's a bit more
  interesting of a test case.

- Test X25519 low order point rejection.

- Test truncating and extending the key share for all cases.

- Run X25519 tests in X25519-based hybrids as well.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.

To file a security issue, use the Chromium process and mention in the report this is for BoringSSL. You can ignore the parts of the process that are specific to Chromium/Chrome.
