ci: TrueAsync integration pipeline (GitHub Actions)

Mirror of the php-temporal pipeline from the SDK side: build the
true-async/php-src fork (shared cache key), the vendored core c-bridge and
the extension from true-async/php-temporal@main, start the Temporal dev
server, then run every tests/truasync/*.php against the built stack.
