Document hostcalls::dispatch_http_call

I think functions should be documented to make it easy to find (regardless of the ABI, which is now being written, cf. proxy-wasm/spec#41)

is there any issue here ?

It doesn't pass tests (see Clippy failures).

Also, I believe that @mpwarres and @martijneken are currently working on the documentation for the whole SDK, so it might be worth waiting a bit for it for the sake of consistency. @mpwarres @martijneken do you have status update?

/// # Returns
///
/// A Result indicating the success or failure of the HTTP call. If the call is successful, the function returns an HTTP status code as a u32. If an error occurs, an Error object is returned.

There may be some problems with this description. It seems that the return is not an HTTP status code, but the code looks more like a token_id

@PiotrSikora : is this still relevant or shall I close it ?

@mpwarres : could you please tell if this PR is still relevant or is obsolete (due to the latest work on docs, etc) ?
