Move restricted traces to CIPD.

All traces are now stored as DEPS entries in CIPD. The auto-generation
script generates the DEPS entries. Note that we don't include DEPS in
the list of generated outputs to simplify other rollers. Also we update
auto-generation to include full sources list to allow 'gn analyze' to
work successfully.

Usees a trace fixture for common code. This will enable a more compact
trace without as much repeated code. We must land a set of re-trace
traces to avoid breakage. 

Also includes a python script for uploading new traces to CIPD. The
script first checks if traces are already present in the cloud, and if
so it skips the upload. It will take a while to complete as the number
of traces grows larger as it takes a few seconds per trace.

The traces in this patch are also re-traced to use the common fixture
code instead of including duplicated code in each trace. They now form
a simple common interface and the autogenerated cpp is now simply a list
of properties.

I've also updated the capture/replay tests to use the simpler common
entry point integration. There is less auto-generated glue code now.
We now use a new serialized string query extension instead of calling
directly into ANGLE's internals.

Also includes a docs update. The capture/replay sample is broken and
we'll need to update it in a follow-up CL. Also includes a few necessary
fixes to the retracing script.
