Fix use after free in MasqueServerBackend

This fixes some crashes in CloseBackendResponseStream that
were due to the fact that QuicConnection gets destructed before
the QuicSimpleServerBackend::RequestHandler is. Since we only
need to hold this memory to ensure the request handler is tracked,
we instead keep a vector of them per connection and clear the
entire vector when the connection goes away.

This code isn't used in production.
