We also changed the interface update interval in the Loading block index DB section, which improves the performance of element iteration.
- declare all synchronization primitives as local variables within LoadBlockIndexGutsFast() - use a lambda for the worker function it becomes easier to understand and maintain the code since all related components are grouped together.
In the C++ standard library, the data structure std::queue does not automatically release memory after removing all elements because std::queue is based on a container that retains allocated memory even when it becomes empty. We made the fast guts load implementation optional with the `-fastguts` flag. It offers nearly double the loading speed but also doubles memory consumption.

The new
LoadBlockIndexGutsFastimplementation, enabled with the-fastgutsargument, utilizes a Thread Pool and parallel processing of disk block indexes to achieve twice the loading speed, though it also doubles memory consumption.Without
-fastguts, this PR still provides a performance boost of approximately 25% for guts loading, thanks to optimizations in other parts of the code.
