With this CL, following InputMethodManager APIs are fully supported
under multi-user / multi-profile environment.
* InputMethodManager#getInputMethodList()
* InputMethodManager#getEnabledInputMethodList()
* InputMethodManager#getEnabledInputMethodSubtypeList()
Those APIs should return appropriate results based on caller's user
ID, even when called from a background user.
There should be no behavior difference if those APIs are called from
the current user process.
This CL also adds -u <user id> option to 'adb shell ime list' command.

Test: make -j cts && atest CtsInputMethodServiceHostTestCases
Test: Manually verified that 'adb shell ime list -a -s -u <user id>'
works, including <user id> == 'current' and 'all'.
