internal/frontend,middleware: add a handler for page statistics

If the GO_DISCOVERY_SERVE_STATS env var is true, add a /detail-stats
handler that handles any detail page, but instead of serving the page
it serves JSON with page statistics, like timings and size.

Implemented as middleware that runs the actual detail handler,
bypassing the cache.

Will be useful for performance work, like forthcoming doc rendering
changes.
