Merge bitcoin/bitcoin#21989: test: Use COINBASE_MATURITY in functional tests
bfa9309ad606102f24c9bd3c33dfe78949f09418 Use COINBASE_MATURITY constant in functional tests. (Kiminuo)
525448df9dc2ab6b7e960ff138956ae3e2efdf60 Move COINBASE_MATURITY from `feature_nulldummy` test to `blocktools`. (Kiminuo)

Pull request description:

  `COINBASE_MATURITY` constant was added to `feature_nulldummy` test in #21373. This PR moves the constant to `blocktools.py` file and uses the constant in more tests as suggested [here](https://github.com/bitcoin/bitcoin/pull/21373#discussion_r605418462).

  Edit: Goal of this PR is to replace integer constants with `COINBASE_MATURITY` but not necessarily in *all* cases because that would mean to read and fully understand all tests. That's out of my time constraints. Any reports where `COINBASE_MATURITY` should be used are welcome though!

"""Test the wallet backup features.
Test case is:
4 nodes. 1 2 and 3 send transactions between each other,
fourth node is a miner.
1 2 3 each mine a block to start, then
Miner creates 100 blocks so 1 2 3 each have 500 mature
coins to spend.
Then 5 iterations of 1/2/3 sending coins amongst
themselves to get transactions in the wallets,
and the miner mining one block.
Wallets are backed up using dumpwallet/backupwallet.
Then 5 more iterations of transactions and mining a block.
Miner then generates 101 more blocks, so any
transaction fees paid mature.
Sanity check:
Sum(1,2,3,4 balances) == 114*500
1/2/3 are shutdown, and their wallets erased.
Then restore using wallet.dat backup. And
confirm 1/2/3/4 balances are same as before.
Shutdown again, restore using importwallet,
and confirm again balances are correct.
