Remove optional::value(), map::at() from quic.

QUICHE is not supposed to have exceptions. std::optional::value can
throw bad_optional_access, and absl_flat_hashmap::at can throw
out_of_range.

There are other places where we use exception-throwing APIs in
QUICHE, but I'll tackle those in future changes.
