This adds support for printing the full call stack when a leak is reported
by the checked memory allocator. An `ARROW_CHECKED_MAX_RETAINED_FRAMES`
environment variable controls how many frames are retained. To keep this
completely backwards-compatible, the default right now is zero. In this case,
the reported error is exactly the same as before. When a higher value is given
though, a longer call stack is printed. For example:
Before (same as `ARROW_CHECKED_MAX_RETAINED_FRAMES=0`):
```
checked_allocator.go:160: LEAK of 64 bytes FROM
github.com/apache/arrow/go/v12/arrow/array.(*TimestampBuilder).newData line 2396
```
After (with `ARROW_CHECKED_MAX_RETAINED_FRAMES=100`):
```
checked_allocator.go:160: LEAK of 64 bytes FROM
github.com/apache/arrow/go/v12/arrow/array.(*TimestampBuilder).newData line 2396
