plugins.huya: fix stream URLs

[bastimeyer]

Set Referer and Origin headers, keep only necessary query string params in the stream URLs, and remove stream URL HEAD request.

Fixes #5784

No idea if this is valid for all channels.

Random channel test:

for cdn in $(streamlink --json huya.com/shege | jq -r '.streams | keys[] | select(contains("source_"))'); do
    timeout 20 streamlink -o /dev/null huya.com/shege $cdn
    echo
done

Did another check and apparently there's a TLS/SSL issue on one of their CDNs (source_hy). I've added a stream priority override, so it's not listed as "best".

Going to merge now...
