src: gate all quic behind disabled-by-default compile flag

Due to quictls/openssl@93ae85b it is
clear that we will need to revert back to using OpenSSL's official releases. This means we will
be forced to re-implement at least part of the underlying QUIC implementation to use different
crypto APIs. For that reason, this PR disables building any of the QUIC support by default and
introduces a new compile time flag.
