Describe the bug

The Node adapter currently sends back the Vary: Accept-Encoding header as part of the response (when files under /_app like .js and .css files are requested) even when the precompress configuration option is false; meaning even when the response won't vary based on the Accept-Encoding header of the request, which is what Vary: Accept-Encoding is supposed to indicate.

In summary, adapter-node should not include Vary: Accept-Encoding in the response if precompress: false.

Reproduction

Just build a SvelteKit Demo App with adapter-node and send a request using curl -i to some CSS/JS file, and examine the response headers.
