Defer top process state for VM

The top state will make JIT compilation easier to be triggered.
To reduce the impact of startup time, if there is launching activity,
the top state will be deferred to apply until idle or 1s timeout.
The cold launch time of Contacts, Phone, Calculator are reduced ~15ms.

Test: AppLaunchTest
