Avoid exception from 'adb shell ime enable/disable'

This is a preparation to introduce CTS for per-profile IME.

Currently
  adb shell ime enable <ime id>
and
  adb shell ime disable <ime id>
can throw IllegalArgumentException when <ime id> is not recognized by
the system.  This makes some sense, but if we start supporting
'-u all' option it'd make more sense if it just shows an error message
rather than letting the command crash with throing an exception.

This behavior change also removes a limitation that developers cannot
use
  adb shell ime disable <ime id>
command to remove an IME ID from Settings.Secure.ENABLED_INPUT_METHODS
if that IME is not currently installed.

Bug: 120784635
Test: Manually verified as follows.
  1. Build aosp_blueline-userdebug and flash it
  2. adb shell ime enable com.example.android.softkeyboard/.SoftKeyboard
     -> "Unknown input method <IME ID here> cannot be enabled"
  3. adb shell ime disable com.example.android.softkeyboard/.SoftKeyboard
     -> "Input method <IME ID here>: already disabled"
