The ArrayEquals, ArrayHashCode, ArrayToString, and

demoted from errors to warnings. Fix existing

With CL[1],[2] to migrate InputMethodService as the subclass of the new
introduced class WindowProviderService in S_V2, IME context resources
can be managed by associating the window container of IME window when
its display/window configuration changed.

So we can get rid of createDisplayContext logic from S_V2 with gated
by SDK version and refining the method of get IME context with
documentation to make it clear.

As CL[1] introduces diplayContext to address
IME service context's Resources / DisplayMetrics update when
switching IME window to another display after onConfigurationChange.

In LatinIME#onInitializeInterface, we only update keyboard theme context
and displayContent when the displayId is changed, but overlooked even
the displayId is the same, the display context's resource configuration
might changed like the device orientation changd.

It leads getDefaultKeyboardHeight will get wrong config_max_keyboard_height
fraction value when rotating to landcape because the context resources
didn't get updated.

Add a check to update keyboard theme context when the current display
configuation is changed accordingly.
