mpv_gl: add network streaming tuning options

Browse Source 
behavior change: mpv now uses explicit cache=yes, cache_pause=no
(stutter over pause for short clips), 50MiB demuxer buffer cap,
20s read-ahead, and 10s network timeout (down from ~60s default).
Improves first-frame latency on uncached video streams and surfaces
stalled-connection errors faster.

# Network streaming tuning for the uncached-video fast path.
# cache=yes is mpv's default for network sources but explicit
# is clearer. cache_pause=no keeps playback running through
# brief buffer underruns instead of pausing — for short booru
# clips a momentary stutter beats a pause icon. demuxer caps
# keep RAM bounded. network_timeout=10 replaces mpv's ~60s
# default so stalled connections surface errors promptly.
