Addressed a number of comments, and rebased on top of #31802.

I will however not have (much) time to push this further forward until the end of this month. @Sjors or @ryanofsky, or someone else, feel free to take this over and/or integrate into other PRs.

Another attempt at #25380 with an alternate approach

This PR updates `CBlockPolicyEstimator` to ignore all transactions that are CPFP'd by some child when a new block is received.
This fixes the assumption that all transactions are confirmed solely because of their fee rate.
As some transactions are confirmed due to a CPFP by some child.



This approach linearize all transactions removed from the mempool because of the new block, and only ignore transactions whose mining score is not

This is listed on https://doc.qt.io/qt-5.15/linux-requirements.html as "recommended", and doesn't seem to be needed (only used for windowing over multiple screens support?) , and the fact that it's no-longer installed by default on modern linux distros (i.e Ubuntu), is annoying/confusing for users.

cACK 413c81b134a16403cc0f64e21c3c0967c211b318

This change makes much sense to me, if the min relay fee is lowered the feerate tracking should also take that into account.

(https://github.com/bitcoin/bitcoin/pull/33199#discussion_r2285915354)
I was wondering if the new test could be avoided by defining `low_feerate` as MINIMUM_RELAY_FEE_RATE in the previous test `test_estimation_modes`.

📝 ismaelsadeeq opened a pull request: "fees: refactor: Create `policy/fees` dir and rename `fees.{h, cpp}` to `fees/block_policy_estimator{h, cpp}`"
(https://github.com/bitcoin/bitcoin/pull/33218)
This PR is a simple refactoring that does four things:

1. Renames `test/policy_fee_tests.cpp` to `test/feerounder_tests.cpp`.
2. Renames `policy/fees.{h,cpp}` to `policy/fees/block_policy_estimator.{h,cpp}`.
3. Renames `policy/fees_args.cpp` to `policy/fees/block_policy_estimator_args.cpp`.
4. Modifies `estimateSmartFee` to return the block height at which the estimate was made by adding a `best_height` unsigned int value to the `FeeCalculation` struct.

**Motivation**

In preparation

I separate the refactoring commits (first four) into it's own PR in https://github.com/bitcoin/bitcoin/pull/33218

Hence putting this in draft.

📝 ismaelsadeeq converted_to_draft a pull request: "Fees: add Fee rate Forecaster Manager"
(https://github.com/bitcoin/bitcoin/pull/31664)
- This PR implements the core component of #30392, introducing a new fee rate forecasting module.
The primary addition is a `ForecasterManager` that coordinates multiple forecasting strategies to be able to provide better transaction fee rate predictions.


### Key Changes

1. **Refactoring of `CBlockPolicyEstimator`**
- Renames `fees` to `block_policy_estimator` for clarity.
- Renames`fees_args` to `block_policy_estimator_args` for clarity
- Renames `policy_fee_tests` t

Maybe after https://github.com/bitcoin/bitcoin/pull/32750 can use CFeeRate to keep consistency with the rest of the code.
