commit b52eed52ccc3297b87781e9b8a97622a44176119
Author: bsheedy <bsheedy@chromium.org>

Add app button to VR controller test actions

Adds the ability to press the app button via the Chrome VR native
controller input code and switches all uses of app button presses over
to it. This is should fix all the flakiness we've been seeing with
the app button-related tests, as we're no longer relying on the flaky
VrCore-side controller emulation.

As a side-effect, also adds gesture detection capabilities when using
the controller input code since app button short/long presses require
it. This currently only supports button click detection, but could
be easily extended later on to support scrolling, etc.

Use mocked VR controller for scrolling

Switches all VR instrumentation tests for scrolling using the Daydream
controller to use the Chrome-side controller mock instead of the
VrCore-side emulation via intents. The latter has always been somewhat
flaky, so this should help reduce VR test flakiness.
