[fetch] Fix sporadic data corruption bug in HTTP client and add fast path

- This removes memory pooling from the HTTP client which sometimes caused invalid memory to be written to the response body.
- This adds a fast path for small HTTP/HTTPS responses that makes it a single memory allocation for the response body, instead of copying & allocating a temporary buffer
