Report active extensions in crash reports. This only implements Windows right now. Mac and linux will be separate CLs.

"Active" is overloaded to mean different things depending on
the process type:

- browser: all enabled extensions
- renderer: unique set of extensions from all user scripts
- extension: extensions running in the process
