Reviewed by Simon Fraser.

The GraphicsLayer Tree can get quite large which exceeds the OS Log's
printing limits, even with the Enable-Oversize-Messages OS Log option.
WTFLogAlways will print to both stderr and the OS Log but on iOS its not
easy to get access to stderr without having a debugger attached. This
change will additionally print the tree output to a temporary file which
can be read more easily to aid in debugging when access to stderr is
limited.
