This CL adds ACTION_CLICK or ACTION_LONG_CLICK actions to a key node
info. But report a node info without these actions for the same key
while hovering to avoid announcement "double tap to select and double
tap and hold to long press".

It should be disabled when it is empty. But should be enabled even
when it is empty with accessibility exploration on to avoid announcing
"disabled".

Note that this CL may not be able to handle "suspending talk back"
state correctly. It should be handled by registering
TouchExplorationStateChangeListener that is available from API 19.

Because EmojiPageKeyboardView doesn't use PointerTracker to handle
MotionEvent, a dedicated accessibility delegate is needed. Then the
recent tab can be updated even with accessibility mode on.

Because a keyboard handling hover events and determining a virtual
node by itself, there is no need to supply whole virtual nodes info
for the keyboard. Just returning an empty accessibility node info
supresses annoucements of all keys.

This CL also fixes the undefined virtual id value.

The previous time out was 1500 milliseconds that wasn't enough for
announcing some accented letters, for example "Ü". This CL makes the
time out to 3000 milliseconds.

A more keys keyboard may have a divider on it. The MoreKeysDetector
should be used even with accessibility mode on to be able to handle a
divider.

With accessibility mode on, hover events for a more keys keyboard are
handled among MoreKeysKeyboardAccessibilityDelegate and
MoreKeysKeyboardView. But the more keys keyboard is shown by
MainKeyboardAccessibilityDelegate that uses PointerTracker to handle
hover events. Thus we need to clear PointerTracker state when the more
keys keyboard is dismissed.

This is a workaround to resolve the issue. We should reconsider the
structure of those views and accessibility delegates in the future.
