Remove unnecessary query in IMMS#switchUserOnHandlerLocked() (2nd try)

This is the 2nd attempt of submitting my previous CL [1], which got
reverted [2] due to a boottime regression (Bug 329414077).
We have already addressed the major contributor of the boot time
regression [3], so this CL should be ready to be submitted again.

This is a follow up CL to my previous CL [4], which started using

  InputMethodSettingsRepository

as a on-memory data repository of InputMethodSettings to avoid
unnecessary queries to PackageManagerService again.

With this CL

  InputMethodManagerService#switchUserOnHandlerLocked()

also start using InputMethodSettingsRepository instead of querying
available IMEs for the new user dynamically.

This CL is supposed to improve the IME user switching latency.
