Implement fuzzer mode for ECH server.

Now skipping over HPKE decryption in |ssl_client_hello_decrypt| when
fuzzer mode is enabled. To improve code coverage, this fuzzer-only logic
also also has the ability to simulate a failed decryption.

As a result of mostly skipping the decryption, we now have to exclude
"*-ECH-Server-Decline*" tests from running in fuzzer mode. These tests
rely on the now-broken assumption that decryption will fail when the
client used an ECHConfig unknown to the server.

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.
