Filtering Oblivious DoH

[ameshkov]

Issue Details

We recently enabled filtering of DoH by default: https://github.com/AdguardTeam/CoreLibs/issues/1563

However, Safari in Private browsing went further and they use Oblivious DoH (1):

Private Browsing uses Oblivious DNS over HTTPS by default, which encrypts and proxies DNS queries to protect the privacy and integrity of these lookups.

Proposed solution

We should be able to filter ODoH on-the-fly just like we do with the regular DoH.

Alternative solution

No response
