emulator: Enable dex-preoptimization
This enables the Dex pre-optimization for emulator-specific builds.
The idea is to speed up the initial boot sequence of an SDK AVD by
avoiding the costly on-device preopt pass that is performed otherwise
the first time the AVD is launched.
Benchmarking shows reductions in first boot time from 1m30s to 40s
on a 2.4GHz Xeon when emulating the AOSP master ToT.
