Used to investigate #5583 and other issues like it (stack overflows) by
figuring out which functions' stack frames contribute most to an
overflowing stack.

Test Plan:

Used in an LLDB debug session, e.g.:

```
$ rust-lldb ~/sui/target/debug/deps/sui-core-.... test_move_call_mutable_object_not_mutated
(lldb) command script import ~/sui/scripts/lldb_frame_sizes.py
(lldb) run
(lldb) frame-sizes
```

Example output:
