trace_processor: improve trace processor's iterator API This CL makes three changes: 1. Adds a GetColumnName(uint32_t) method to the iterator. This allows users of the iterator API to print out column names if they want to. 2. Simplifies the result of Next to a boolean. This allows users to place iterator.Next() calls in the conditional of their for loop. This also means GetLastError() should be called when Next() returns false to check whether we had a true EOF or an erroneous EOF. 3. Removes IsValid(). This can be folded into Next() especially if we have Next() being called in For loops. Bug: 118867986 Change-Id: Ifd4ff64b236794a2b59ca0d5839d5072f590bcbd
