Workaround compilation reset unavailable on user builds
* cmd package compile --reset does not work on user builds.
* To work around this, we copy the apk to the tmp directory, and then kick off an un-install and a re-install.
* A side-effect of uninstalling / re-installing is that ART profiles end up in vfy, which is the state we expect.
* Added `compilation.enabled` as an instrumentation test argument, to disable this behavior if the benchmark wants
full control on CompilationModes.

Bug:
Relnote: "Fixed an issue where compiled methods were not correctly being reset between each macrobenchmark on unrooted builds. This unfortunately requires reinstalling the apk each iteration, which will clear application data for each macrobenchmark."

Should we fix --reset? I haven't tested, but it looks like it's just a matter of changing enforceSystemOrRoot to enforceSystemOrRootOrShell on
