Take state snapshot in IMMS#attachNewInputLocked()
With this CL, we can finally start taking a state snapshot every time
IMMS#attachNewInputLocked() gets called, which allows us to include
the last N (currently set to 16) history of such snapshots in dumpsys
from InputMethodManagerService:
adb shell dumpsys input_method
This is a huge milestone for us to start relying more on historical
debugging rather than logcat-based debugging.
Test: Run `adb shell dumpsys input_method` to make sure that
"mStartInputHistory" entries are updated.
