Dave Lee 1da4494184 [lldb] Add comment on cross printing of summary/value (#81681) ...

Adds a comment to indicate intention of a piece of value printing code.

I was initially surprised to see this code (distilled for emphasis):

```cpp
if (str.empty()) {
  if (style == eValueObjectRepresentationStyleValue)
    str = GetSummaryAsCString();
  else if (style == eValueObjectRepresentationStyleSummary)
    str = GetValueAsCString();
}
```

My first thought was "is this a bug?", but I realized it was likely intentional. This 
change adds a comment to indicate yes, this is intentional.
