b922f6b526 rpc: scanblocks, add "completed" flag to the result obj (furszy)
ce50acc54f rpc: scanblocks, do not traverse the whole chain block by block (furszy)
Pull request description:
Coming from https://github.com/bitcoin/bitcoin/pull/23549#pullrequestreview-1105712566
The current `scanblocks` flow walks-through every block in the active chain
until hits the chain tip or processes 10k blocks, then calls `lookupFilterRange`
function to obtain all filters from that particular range.
This is only done to obtain the heights range to look up the block
filters. Which is unneeded.
As `scanblocks` only lookup block filters in the active chain, we can
directly calculate the lookup range heights, by using the chain tip,
without requiring to traverse the chain block by block.

To tell the user whether the process was aborted or not.
Plus, as the process can be aborted prior to the end range,
have also changed the "to_height" result value to return the
last scanned block instead of the end range block.
This commit updates the code by replacing the RPC call used to
decode an address and retrieve its corresponding scriptpubkey
with the address_to_scriptpubkey function. address_to_scriptpubkey
function can now decode all addresses formats, which makes
it more efficient to use.

Pull request description:
When a pre-mined blockchain is used (default behavior), it [contains coinbase outputs in blocks 76-10](07c54de550/test/functional/test_framework/test_framework.py (L809-L813)) to [the MiniWallet's default address](07c54de550/test/functional/test_framework/wallet.py (L99-L101)). That's why we always* `rescan_utxos()` after initializing the MiniWallet, in order for the MiniWallet to account for those mature UTXOs.
> The tests following this usage pattern can be seen with:
> ```git grep -n "MiniWallet(" $(git grep -le "rescan_utxos()" $(git grep -Le "self.setup_clean_chain = True"))```
**This PR adds `rescan_utxos()` inside MiniWallet's initialization to simplify usage when the MiniWallet is used with a pre-mined chain.**
### secondary changes
- *There are a few tests that use the pre-mined blockchain but do not `rescan_utxos()`, they instead generate new blocks to create mature UTXOs.
> Those were written before the `rescan_utxos()` method was introduced with https://github.com/bitcoin/bitcoin/pull/22955 (fac66d0a39) and can be seen with:
> `git grep -n "MiniWallet(" $(git grep -Le "rescan_utxos()" $(git grep -Le "self.setup_clean_chain = True"))`
>
After including `rescan_utxos()` inside MiniWallets initilization, this blocks generation logic is not needed as the MiniWallet already accounts for enough mature UTXOs to perform the tests. **Therefore the now redundant blocks generation logic is removed from those tests with the second commit.**
- The rest of the MiniWallet tests use a clean chain (`self.setup_clean_chain = True`) and can be seen with
`git grep -n "MiniWallet(" $(git grep -le "self.setup_clean_chain = True")`
From those, there are a few that start from a clean chain and then create enough mature UTXOs for the MiniWallet with this kind of logic:
07c54de550/test/functional/mempool_expiry.py (L36-L40)
**Those tests are simplified in the third commit to instead utilize the mature UTXOs of the pre-mined chain.**
