This patch makes it so that we launch the RDD process relatively early in the Firefox startup. This will improve the latency when we began playback for the first video. Differential Revision: https://phabricator.services.mozilla.com/D229427

<!-- This file tests the saving and loading of memory reports to/from file in
|

about:memory in the presence of child processes. It is also notable
|
|
for being an about:memory test that uses the real reporters, rather
|
|
than fake deterministic ones, and so tends to show up problems in the
|
|
real reporters (like bogus negative values). -->
