cmake: add `BUILD_EXAMPLES` option to build examples

You can enable it with `-DBUILD_EXAMPLES=ON`.

To match autotools' `make examples` feature.
Windows (static) builds not tested.

Also enable examples in a pair of CI jobs.

Apply related updates to the macOS CI workflow:
- drop unused `CXX` envs.
- drop no longer needed `-Wno-error=undef -Wno-error=conversion` flags.
- pass `-Wno-deprecated-declarations` to GCC too (for `BUILD_EXAMPLES`).
- document why `-Wno-deprecated-declarations` is necessary.

http3: quiche+ngtcp2 improvements

- quiche: error transfers that try to receive on a closed
or draining connection
- ngtcp2: use callback for extending max bidi streams. This
allows more precise calculation of MAX_CONCURRENT as we
only can start a new stream when the server acknowledges
the close - not when we locally have closed it.
- remove a fprintf() from h2-download client to avoid excess
log files on tests timing out.

mbedTLS: implement CURLOPT_SSL_CIPHER_LIST option

Use a lookup list to set the cipher suites, allowing the
ciphers to be set by either openssl or IANA names.

To keep the binary size of the lookup list down we compress
each entry in the cipher list down to 2 + 6 bytes using the
C preprocessor.

dllmain: Call OpenSSL thread cleanup for Windows and Cygwin

- Call OPENSSL_thread_stop on thread termination (DLL_THREAD_DETACH)
to prevent a memory leak in case OpenSSL is linked statically.

- Warn in libcurl-thread.3 that if OpenSSL is linked statically then it
may require thread cleanup.

OpenSSL may need per-thread cleanup to stop a memory leak. For Windows
and Cygwin if libcurl was built as a DLL then we can do that for the
user by calling OPENSSL_thread_stop on thread termination. However, if
libcurl was built statically then we do not have notification of thread
termination and cannot do that for the user.

Also, there are several other unusual cases where it may be necessary
for the user to call OPENSSL_thread_stop, so in the libcurl-thread
warning I added a link to the OpenSSL documentation.
