Description

Add burnt UTXOs to the list of sidechain UTXOs that the second layer queries

Motivation and Context

The second layer queries only sidechain-relevant UTXOs. Burns were excluded, but need to be included in order to be scanned

How Has This Been Tested?
---
Manual testing with second layer scanner
