Sync HAVE_* definitions for extensions

This syncs missing build system gaps of some extensions' definitions
being defined on Windows and some on *nix. To not cause too much
divergence with the current default ext/skeleton template, they weren't
removed even though they aren't used. Help texts are also synced a bit
where possible.

* HAVE_INTL (added to Autotools also)
* HAVE_PDO_DBLIB (added to Windows build also)
* HAVE_PDO_FIREBIRD (added to Windows build also)
* HAVE_TOKENIZER (added to Autotools also)
