Dynamic HTTPS record rewrite with $dnsrewrite (CNAME flattening) not working

### The problem

Related and solved: https://github.com/AdguardTeam/AdGuardHome/issues/8276

Software version: adguardhome v0.107.78 and chrome 150.

I want to overwrite the HTTPS record of domain A with the dynamically fetched HTTPS record of domain B with `$dnsrewrite`. I do that with a CNAME record and it doesn't work in chrome.

Steps to reproduce:

- add adguardhome rules, `||what.a.ever^$dnstype=HTTPS,dnsrewrite=NOERROR;CNAME;what.b.ever`.
- check the HTTPS record of `what.a.ever` with an dns query utility, e.g. https://github.com/natesales/q, it returns both CNAME `what.b.ever` and HTTPS record from `what.b.ever`.
- access `https://what.a.ever` in chrome, and with the correct HTTPS record, ECH should be enabled, but is disabled.

### Proposed solution

When querying HTTPS record from AdGuardHome, it should emphasize HTTPS record instead of CNAME record.

### Alternatives considered and additional information

There are several domains for ECH testing, e.g.

- https://defo.ie/ech-check.php
- https://crypto.cloudflare.com/cdn-cgi/trace
- https://tls-ech.dev
