Issue 49012: Breakpad Processor: Rename 'StackFrameInfo' structure to 'WindowsFrameInfo'.

Browse source 
Also, rename stack_frame_info.h to windows_frame_info.h.

If it seems odd to have functions like FillSourceLineInfo returning
Windows-specific data structures... well, it is! This patch just makes
it more obvious what's going on.
