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.

# An example hgweb CGI script, edit as necessary
# See also https://mercurial-scm.org/wiki/PublishingRepositories

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()
