<summary>
Records the amount of time it takes for {Settings} in ambient mode to start.
This includes tasks such as downloading an initial set of photos from IMAX
server, decoding them, loading the animation from resource pak, etc. Note
this measurement does not include the lock screen inactivity timeout
(currently 7 seconds). So ideally, this should be 0. Also note that ambient
mode should start after a 10 second timeout if at least 1 photo has been
downloaded from IMAX. Hitting the 10 second timeout is considered non-ideal,
but acceptable behavior. However, anything over that is very bad. Thus, this
histogram has a 15 second maximum (added a 5 second buffer to the timeout
just to be safe). Anything over the 15 second maximum goes in the overflow
bucket and is considered a total failure to start ambient mode. This should
be extremely rare. Emitted each time the {Settings} UI starts rendering, or
when ambient mode exits in the event that the UI never started rendering.

Only applies to ambient video themes. Tracks the total number of frames
created divided by the total number of frames expected during the entire
ambient session. 100% represents ideal smoothness, and any deviation from
that is due to dropped video frames. This metric requires a minimum of ~5
seconds of playback (~100 expected videos frames) to be recorded; ambient
video sessions shorter than that are not statistically significant enough to
record and will not be tracked. As such, this metric is just a general gauge
of the video's performance in the field. Separate fine-grained metrics
tracking rebuffering frequency and duration may be added in the future.
