Record analytics about package install attempts to Event Log.
The purpose of this change is to provide analytics about the various
stages of the install flow. Recorded information does not contain
user-, device-, or package/app-identifying information.
Examples of recorded information are:
* duration of the flow (start to finish)
* duration of the flow until the moment the user clicks Install
* whether the attempt is an update or a new install.
* whether app verification is enabled.
* whether Unknown Sources is enabled.
* whether the attempt was blocked by Unknown Sources.
* whether permissions were displayed.
* error code (if any) returned by PackageManager when installing the
package.
