fix: chain halt if some invalid asset lock transactions are in mempool (#5648)
## Issue being fixed or feature implemented
As discovered during platform testing by @shumkov , it seems as the
chain can halt in miner if somehow mempool would have several
transactions that are somehow invalid (maybe too low fee or something
else). They can't be mined, but miner can't prepare a valid block with
correct Credit Pool amount.

It is indeed can happen although I haven't reproduced it with functional
tests at the moment 🤷‍♂️

## What was done?
Refactored and simplified a logic of Credit Pool amount of validation
and added one more layer of validation: after all transaction are
actually added to block by miner, it is recalculated one more time.
Also used correct `pindexPrev` instead Tip() for EHF signals.

## How Has This Been Tested?
Before this changes platform failed with this error and chain halt:
```
2023-10-20T06:20:16Z (mocktime: 2023-10-20T06:28:29Z) ERROR: ConnectBlock(DASH): CheckCreditPoolDiffForBlock for block 9d635e1fd0d7a8a5bf16ce158d3a39cbf903864bb6d671769836ea7db6055230 failed with bad-cbtx-asse locked-amount
```
With changes from this PR platform is generate the asset-lock
transactions that are included to block and chain is not halt:
```
2023-10-27T10:45:37Z (mocktime: 2023-10-27T14:37:22Z) GetCreditPoolDiffForBlock: CCreditPool is CCreditPool(locked=32100015, currentLimit=32100015)
```

unit/functional tests are succeed.

What is Dash?

Dash is an experimental digital currency that enables instant, private payments to anyone, anywhere in the world. Dash uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Dash Core is the name of the open source software which enables the use of this currency.

For more information read the original Dash whitepaper.

License

Dash Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.

Development Process

The master branch is meant to be stable. Development is normally done in separate branches. Tags are created to indicate new official, stable release versions of Dash Core.

The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.

Testing

Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Translations

Changes to translations as well as new translations can be submitted to Dash Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
