util: expose an "available" API on compression engines...

util: expose an "available" API on compression engines When the zstd compression engine is introduced, it won't work in all installations, namely pure Python installs. So, we need a mechanism to declare whether a compression engine is available. We don't want to conditionally register the compression engine because it is sometimes useful to know when a compression engine name or encountered data is valid but just not available versus unknown.
