Add GetFullBalance() to compute used balance in getbalances RPC and on GUI [GUI PR #775](https://github.com/bitcoin-core/gui/pull/775)
Check #28776 (review) by @achow101
However, I think it would be better to move all of this into
GetBalanceitself and just have it always compute the used balance for us rather than having the caller do this extra computation.
used balance from GetBalance(...)

My understanding of this part of @achow101 comment was to move the calculation for the used balance to GetBalance(...)
I have updated the PR and added GetFullBalance() which adds used balance to GetBalance(...)

GetBalance include m_mine_used. It’s up to the caller to figure out what to do with that information.

My understanding from the above line is min_depth should be zero when calculating full_balance hence I didn’t include the statement below in the above if since it uses min_depth provided by the caller
I didn’t include the check in this if since tx_depth is always >= 0
