Merge #19752: test: Update wait_until usage in tests not to use the one from utils
d841301010914203fb5ef02627c76fad99cb11f1 test: Add docstring to wait_until() in util.py to warn about its usage (Seleme Topuz)
1343c86c7cc1fc896696b3ed87c12039e4ef3a0c test: Update wait_until usage in tests not to use the one from utils (Seleme Topuz)

Pull request description:

  Replace global (from [test_framework/util.py](https://github.com/bitcoin/bitcoin/blob/master/test/functional/test_framework/util.py#L228)) `wait_until()` usages with the ones provided by `BitcoinTestFramework` and `P2PInterface` classes.

  The motivation behind this change is that the `util.wait_until()` expects a timeout, timeout_factor and lock and it is not aware of the context of the test framework. `BitcoinTestFramework` offers a `wait_until()` which has an understandable amount of default `timeout` and a shared `timeout_factor`. Moreover, on top of these, `mininode.wait_until()` also has a shared lock.

  closes #19080
