Hook up the memory purger to all the relevant locations.
This removes the two-state purge/reset code (no longer necessary), and the hooks to the power monitor (not ready to turn those on without more work and testing).
BUG=23400
TEST=Run Chrome with --purge-memory-button, use it for awhile, open the Task Manager, and click "Purge Memory". You should still be able to use the program normally, and hopefully we dumped some memory out too (varies by usage).
