Subject: [PATCH 1/2] feat: update bindings to Pact FFI 0.5.12

Add `sync_message_match_response_contents`, which wraps the function
introduced in 0.5.12. It matches actual contents against an expected
response of a synchronous message with the response's matching rules,
as the verifier does. It returns the mismatches as a list of JSON
objects, empty when the contents match.

The header now declares the `pactffi_register_plugin_log_callback`
parameter as a function pointer, so the build hook only patches
`pactffi_register_log_callback` (pact-reference#544). The header no
longer defines a `PluginLogCallback` type, so the CFFI callback is
created from the explicit function pointer signature.

0.5.12 also guarantees that a replaced log or plugin log callback is
not running and is not invoked again once registration returns. The
docstrings of both register functions now state this.

All upstream documentation links now point at 0.5.12. The links into
the pact-reference repository use the `pact_ffi-v` tag prefix.
