The LibCore sockets implementation becomes WebSocketImplSerenity.
This will allow us to create a custom WebSocketImpl subclass for Qt
to use in Ladybird.
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
As LibTLS now supports the Core::Stream APIs, we can get rid of the
split paths for TCP/TLS and significantly simplify the code as well.
Provided to you free of charge by the Core::Stream-ification team :^)
