sp_BlitzCache: add Azure SQL DB/MI bypass to version gate

The LIKE '12%' pattern in the version check would incorrectly block
Azure SQL DB, which reports ProductVersion starting with '12.' despite
supporting 2016+ features. Add an EngineEdition IN (5,6,8) check as
the first CASE branch to allow Azure SQL DB, Managed Instance, and
Synapse through both version gates.
