Remove support for SSL compression

Browse Source 
PostgreSQL disabled compression as of e3bdb2d and the documentation
recommends against using it since.  Additionally, SSL compression has
been disabled in OpenSSL since version 1.1.0, and was disabled in many
distributions long before that.  The most recent TLS version, TLSv1.3,
disallows compression at the protocol level.

This commit removes the feature itself, removing support for the libpq
parameter sslcompression (parameter still listed for compatibility
reasons with existing connection strings, just ignored), and removes
the equivalent field in pg_stat_ssl and de facto PgBackendSSLStatus.

Note that, on top of removing the ability to activate compression by
configuration, compression is actively disabled in both frontend and
backend to avoid overrides from local configurations.

A TAP test is added for deprecated SSL parameters to check after
backwards compatibility.

Bump catalog version.

SSL compression is nowadays considered insecure and its use is no

compression by default, and many operating system distributions
disable it in prior versions as well, so setting this parameter to on
