Description
Currently AdGuard will use DoH2 exclusively for all DoH upstreams that use `https://` URLs.
We should add a low-level setting that enables both DoH3 and DoH2 (it's available as a flag in DnsLibs).
When this flag is enabled, DnsLibs tries to connect using both DoH3 and DoH2 simultaneously and chooses the one that was established faster, and then closes the slower one.
This setting should be disabled by default.
