Add a "Use proxy for hostname lookup" option

Add a UI option for "Use proxy for hostname lookup" option and plumb
it into libtorrent's settings_pack.proxy_hostnames option.  This is
available for SOCKS5 and HTTP proxies, and defaults to true, which
is the previous functionality.  Hostname lookups can be forced to be
local by unchecking this option, which can aid compatibility with
certain non-compliant proxy servers.

Closes #17902.
PR #17904.
