Support hmac-secret capable hardware tokens

[imp1sh]

Summary

It would be nice if any FIDO2 key would work with keepassxc to unlock the vault.

Desired Behavior

Unlock keepassxc datatbase with FIDO2 key.

Possible Solution

Challenge Response seems legit. More details here:
solokeys/solo1#348

Context

I just switched from a yubikey which gave me a static key which Solo key doesn't. Still would like to have a working and secure method to unlock my fault with not only a static password.

FIDO2 has nothing to do with HMAC-SHA1 challenge response. As stated in the response to the issue over at solo key, the key must support the hmac-secret protocol.

This looks like a duplicate of #3560
There's a POC commit posted there, d63e737 if anyone is able to work on it.
