Browser: Add a basic GUI download feature We now allow you to download files by right-clicking a link and then choosing "Download". All files are currently saved to the standard downloads location that we get from Core::StandardPaths::downloads_directory(). In the future, we'll probably want to come up with a more restrictive way of doing the "write to disk" portion of this. We should also improve the ProtocolServer to allow streaming of data instead of writing everything in one big go. At the moment, I'm just pretty happy with this GUI. :^)

Everywhere: Correctly report progress of downloads larger than 4GiB This commit changes the variables used to represent the size and progress of downloads from u32 to u64. This allows `pro` and `Browser` to report the total size and progress of a download correctly for downloads larger than 4GiB.

void did_progress(Optional<u64> total_size, u64 downloaded_size);
ProtocolServer: Stream the downloaded data if possible This patchset makes ProtocolServer stream the downloads to its client (LibProtocol), and as such changes the download API; a possible download lifecycle could be as such: notation = client->server:'>', server->client:'<', pipe activity:'*' ``` > StartDownload(GET, url, headers, {}) < Response(0, fd 8) * {data, 1024b} < HeadersBecameAvailable(0, response_headers, 200) < DownloadProgress(0, 4K, 1024) * {data, 1024b} * {data, 1024b} < DownloadProgress(0, 4K, 2048) * {data, 1024b} < DownloadProgress(0, 4K, 1024) < DownloadFinished(0, true, 4K) ``` Since managing the received file descriptor is a pain, LibProtocol implements `Download::stream_into(OutputStream)`, which can be used to stream the download into any given output stream (be it a file, or memory, or writing stuff with a delay, etc.). Also, as some of the users of this API require all the downloaded data upfront, LibProtocol also implements `set_should_buffer_all_input()`, which causes the download instance to buffer all the data until the download is complete, and to call the `on_buffered_download_finish` hook.

AK+Everywhere: Rename String to DeprecatedString We have a new, improved string type coming up in AK (OOM aware, no null state), and while it's going to use UTF-8, the name UTF8String is a mouthful - so let's free up the String name by renaming the existing class. Making the old one have an annoying name will hopefully also help with quick adoption :^)
