feat: new template with coinbase call (#6226)

Description
---
This adds a new grpc call to take a block template and add coinbases to
it as desired. The callee is required to ensure that the coinbases
amounts provided are correct and per consensus.

Motivation and Context
---
This is to allow external miners to create a block with 1 sided coinbase
utxo's to be added without having to create them as this necessitates
the inclusion of all Tari crypto libraries.

How Has This Been Tested?
---
New unit and cucumber tests
