[VL] Stacktrace-categorized memory allocation dumping for debugging

[zhztheplayer]

Description

The status (dump / log) should be formatted in a way like:

1. Accumulative bytes: 600 MB, peak bytes: 300 MB, current bytes: 120 MB, stack:
(stack trace)
2. Accumulative bytes: 500 MB, peak bytes: 200 MB, current bytes: 80 MB, stack:
(stack trace)
3. Accumulative bytes: 400 MB, peak bytes: 300 MB, current bytes: 70 MB, stack:
(stack trace)
4. Accumulative bytes: 400 MB, peak bytes: 300 MB, current bytes: 50 MB, stack:
(stack trace)

The tricky part is probably how to categorize the stacktraces to avoid too many entries in the status dumping / logging.
