Re-use the getArrayBuffer helper from src/display/fetch_stream.js with PDFNodeStreamReader and PDFNodeStreamRangeReader

Browse Source 
Given that the Node.js code uses standard `ReadableStream`s now, see PR 20594, it can use the same `getArrayBuffer` as the Fetch API implementation.

Also, change the `getArrayBuffer` fallback case to an Error (rather than a warning) since that should never actually happen.
