This is a really non-trivial wallet refactor "effective value" which has been
in the Core queue for a pretty long time. There were a ton of merge conflicts
but they were mostly mechanical (all the benchmarks) or "take the Core side
of the diff" (most of wallet.cpp).
The two nontrivial things were:
* In `SelectCoinsMinConf` in wallet.cpp I had to slightly move the asset
filtering logic (but I didn't change it)
* In `OutputGroup::Insert' in coinselection.cpp I changed the effective
value computation to only consider policyAsset values

Pull request description:
Even after #17458, we still deal with setting fees of an `OutputGroup` and filtering the `OutputGroup` outside of the struct. We currently make all of the `OutputGroup`s in `SelectCoins` and then copy and modify them within each `SelectCoinsMinConf` scenario. This PR changes this to constructing the `OutputGroup`s within the `SelectCoinsMinConf` so that the scenario can be taken into account during the group construction. Furthermore, setting of fees and filtering for effective value is moved into `OutputGroup::Insert` itself so that we don't add undesirable outputs to an `OutputGroup` rather than deleting them afterwards.
To facilitate fee calculation and effective value filtering during `OutputGroup::Insert`, `OutputGroup` now takes the feerates in its constructor and computes the fees and effective value for each output during `Insert`.
While removing `OutputGroup`s in accordance with the `CoinEligibilityFilter` still requires creating the `OutputGroup`s first, we can do that within the function that makes them - `GroupOutput`s.

This adds better test coverage and will make it easier in #20744 to remove our dependency on the two-argument boost::filesystem::absolute() function which does not have a direct equivalent in C++17.

cc3044ccdb fix misleading comment about call to non-existing function (pox)
Pull request description:
The comment seems to be describing the subsequent call to `SyncTransaction` but refers to it as `SyncNotifications`, which is not any function currently in the codebase.
It's best to just remove the "what" aspect of the comment and focus on the "why", which also reduces the risk of similar documentation errors in the future, in case the function ever gets renamed, for example.

Rewrite OutputGroups so that the logic is easier to follow and
understand.
There is a slight behavior change as OutputGroups will be grouped by
scriptPubKey rather than CTxDestination as before. This should have no
effect on users as all addresses are a CTxDestination. However by using
scriptPubKeys, we can correctly group outputs which fall into the
NoDestination case. But we also shouldn't have any NoDestination
outputs.
