simplify utf8 validation of incoming WS lines
...
As of #1483 , websockets entail enforce-utf8, so there's no need
to check globalUTF8EnforcementSetting when handling websockets.

implement candidate compromise proposal for websockets
...
1. Text and binary frames are accepted
2. Text frames are sent by default
3. Binary frames are sent to clients who negotiate `binary.ircv3.net`
4. Non-UTF8 data is not accepted (enabling websockets still enables UTFONLY)

mitigate a potential DoS against websocket listeners
...
Websocket listeners would process an arbitrary number of invalid
(non-text or blank) messages without throttling. This imposes fakelag
on such messages by treating them as blank lines.

don't trim line endings in IRCStreamConn
...
Doesn't help if the line ends with regular \n only,
and the parser has to account for \r and \n anyway
