[HTML5] Disable body_size in fetch.

We were using `Content-Length` from the server when `Content-Encoding`
was not set (i.e. response was not compressed).

Sadly, in CORS requests accessing headers is restricted, and while
`Content-Length` is enabled by default, `Content-Encoding` is not.

This results in the impossibility of knowing if the content was
compressed, unless the server explicitly enabled the encoding header
via `Access-Control-Expose-Headers`.

To keep maximum compatibility we must disable `body_size` completely.
