RPP: track recording time in TimelineController

This is part of the work to get rid of PerformanceModel - next up is the
recordStartTime() method. Unfortunately I cannot remove it fully as the
TimelineHistoryManager relies on it. That is what I am working on next -
but this CL still progresses us by storing the recording time in the
controller and then passing it through, thus ensuring that the
TimelinePanel does not depend on the PerformanceModel to know the time
that the recording started.

Source mirrors

DevTools frontend repository is mirrored on GitHub.

DevTools frontend is also available on NPM as the chrome-devtools-frontend package. It's not currently available via CJS or ES modules, so consuming this package in other tools may require some effort.

The version number of the npm package (e.g. 1.0.373466) refers to the Chromium commit position of latest frontend git commit. It's incremented with every Chromium commit, however the package is updated roughly daily.
