Revert 60357 - Merge 60334 - Add a launchApp method to extension management API.

This makes it possible for new tab replacement extensions to recreate the same
app launch experience as the built-in NTP (pinned tabs, launch containers,
etc.)

Also add the extension version to data we report about extensions via
the management API.

BUG=56325, 55474
TEST=An extension using chrome.experimental.management.launchApp(<id>) should
work to launch an app the same way that app gets launched from the built-in
new tab page.
