This reverts commit 1690992d.

Build.VERSION.SDK_INT is bumped with I4716e71d72b2526fe635079d1b.                                                                                     
We no longer need this workaround.

Make sure if Build.VERSION.CODENAME is "REL" or not when
Build.VERSION.SDK_INT is 19 (KitKat). This is a tentative
workaround until Build.VERSION.SDK_INT is bumped to 20 or
greater.

With this CL, LatinIME starts using
InputMethodManager#shouldOfferSwitchingToNextInputMethod when
available and API level is higher than 19 (KitKat).

Note that relevant settings of LatinIME will be ignored if
InputMethodManager#shouldOfferSwitchingToNextInputMethod is
considered to be available at the moment. We will revisit
here to reorganize the user visible settings before the
new global IME switching mechanism becomes publicly
available.

This change moves the methods that create the subtype display name for
spacebar from MainKeyboardView to SubtypeLocale class, and
consolidates SpacebarTextTests with SubtypeLocaleTests.

This will spare a lot of IPC for Latin IME at the cost of very little
retained memory.
This improves the loading by potentially a lot - between 15 and 30%
when the layout is cached (which should now be the case almost every
time), and half that if it's not. More importantly, it makes the
load time less sensitive to high device load, which is one of the
sore points.

In setup wizard, InputMethodManager may not be able to be aware that
this IME is installed, especially just after the IME is installed via
GooglePlay app and hit the open button on the app to launch the setup
wizard.

The subtype locale name on the spacebar will be suppressed when only
one subtype is enabled and
 - Subtype locale is equal to the system locale.
or
 - Subtype language is equal to the system language but the subtype is
   implicitly enabled.

Thus the "es_ES" system locale chooses "es" subtype keyboard
implicitly but the keyboard doesn't have the subtype name on its
spacebar.

This change also removes Spanish Latin America keyboard.
