wallet: balance_with_params_conf_threshold

[ValuedMammal]

Description

This change attempts to do the following

• Simplify Balance computation by reusing logic from filter_chain_unspents.
• Add an outpoints parameter to give the caller more control of the outputs to consider.
• Rewrite trust_predicate and encapsulate the trust definition in Wallet::is_tx_trusted.

We also discussed deferring more of the logic to CanonicalView::balance once that becomes available in bdk_wallet.
