quic|blob: Potentially improve createBlobReaderStream performance

I am currently looking at the quic implementation code (in order to use it for webtransport). I have seen that the quic implementation uses `createBlobReaderStream` https://github.com/nodejs/node/blob/6f941fcfba50fe7c3a342ed2066770aecaaa9b5a/lib/internal/blob.js#L435 for getting the readable. I am wondering `createBlobReaderStream` recreates functions for every call to pull. My experience with webstreams in the browser (also using V8) suggests that this potentially creates a large number of function objects on the stack. So I wonder, if it is not better to move `readNext` up to the top closure of the function and pass the controller as an argument. This may be important, if you run for example a video stream over a webtransport stream. Or am I am missing something?
