Merge #18766: Disable fee estimation in blocksonly mode (by removing the fee estimates global)

03bfeee957ab7e3b6aece82b9561774648094f54 interface: remove unused estimateSmartFee method from node (Antoine Poinsot)
Pull request description:
If the `blocksonly` mode is turned on after running with transaction
relay enabled for a while, the fee estimation will serve outdated data
to both the internal wallet and to external applications that might be
feerate-sensitive and make use of `estimatesmartfee` (for example a
Lightning Network node).
This has already caused issues (for example https://github.com/bitcoin/bitcoin/issues/16840 (C-lightning), or https://github.com/lightningnetwork/lnd/issues/2562 (LND)) and it seems prudent to fail rather than to give inaccurate values.
This fixes #16840, and closes #16890 which tried to fix the symptoms (RPC) but not the cause as mentioned by sdaftuar :
> If this is a substantial problem, then I would think we should take action to protect our own wallet users as well (rather than hide the results of what our fee estimation would do!).
