Remove ChromeWebApkHost::GetGooglePlayInstallState() check from WebApkInstaller

In the install path:
GetGooglePlayInstallState() == GooglePlayInstallState::SUPPORTED
is checked via ChromeWebApkHost::CanCanInstallWebApk() in
add_to_homescreen_manager.cc and app_banner_manager_android.cc

In the update path:
GetGooglePlayInstallState() == GooglePlayInstallState::SUPPORTED
is not checked. However:
- it should be impossible for the WebAPK to be installed if
  ChromeWebApkHost::CanCanInstallWebApk() does not return true
- updates don't show any UI
