tools: add performance-log-close-tags.py, use in performance-log-viewer

Add a new performance-log-close-tags.py tool, which closes unclosed
tags in incomplete performance logs, allowing the rest of the
perofmance-log tools to process them.  This is necessary for
unfinished progressive logs.

Use the new tool as part of the pipeline in performance-log-viewer.
