player: remove --stream-capture option/property

This was excessively useless, and I want my time back that was needed to
explain users why they don't want to use it.

It captured the byte stream only, and even for types of streams it was
designed for (like transport streams), it was rather questionable.

As part of the removal, un-inline demux_run_on_thread() (which has only
1 call-site now), and sort of reimplement --stream-dump to write the
data directly instead of using the removed capture code.

(--stream-dump is also very useless, and I struggled coming up with an
explanation for it in the manpage.)
