Will changes in how we install ARCore affect this? If so, we may want to implement that first.

Assigning to myself as I have a CL pending that should fix this issue.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/1d0280d6ec272b6f935e877a6fac648ca2a20ef3

commit 1d0280d6ec272b6f935e877a6fac648ca2a20ef3

Start leveraging ARCore SDK's InstallActivity

More significant changes:
- rename nativeOnRequestInstallSupportedArCoreCanceled into
  nativeOnRequestInstallSupportedArCoreResult and add boolean parameter
  to it in order to propagate result of installation
- modify ArCoreJavaUtils to start using ArCoreApk.requestInstall via
  reflection
- notify ArDelegate when ChromeActivity's onResumeWithNative
  gets called
- ArDelegate will notify ArCoreJavaUtils that the activity is
  being resumed

Our current approach of installing ARCore via ArCoreApk.requestInstall() from ARCore SDK makes this bug no longer applicable as we have a different approach of checking the status of installation.
