Make estimatedInputLatency metric more friendly for traces without TTI.

Currently the metric throws an error if the trace does not have TTI
or has multiple TTIs. This makes the metric hard to use since one
usually does not know whether a benchmark has a single TTI or not.

Now instead of throwing the metric skips such traces.

The EIL for interactive time is produced only if the trace has
a single TTI. Once https://crbug.com/692112 is fixed, interactive EIL
will be produced also for traces with multiple TTIs.

Apart from that, the patch adds a new metric that computes
the EIL for the whole timeline.

Catapult

Catapult is the home for several performance tools that span from gathering, displaying and analyzing performance data. This includes:

These tools were created by Chromium developers for performance analysis, testing, and monitoring of Chrome, but they can also be used for analyzing and monitoring websites, and eventually Android apps.
