chore(android/engine): Remove help bubble tool tip

[darcywong00]

Fixes #6734
Rather than fixing the display of the help bubble, we'll remove it for 16.0 and re-implement it in a future release.

This does deprecate the two KMManager calls:

isHelpBubbleEnabled()
setHelpBubbleEnabled()

TODO:

• Update deprecated calls on help.keyman.com (chore: Deprecate developer/android/engine/16.0 help bubble API methods help.keyman.com#617)

User Testing

Setup - Install the PR build of Keyman for Android

• TEST_BASIC - Verifies app still works

1. Launch Keyman for Android and dismiss the "Get Started" menu
2. Verify no help bubble tooltip is displayed on the globe key
3. Short-press the globe key
4. When 1 keyboard is installed, verify the keyboard picker menu is displayed
5. Dismiss the menu

LGTM

I suggest that we implement this in a future version as a native KMW widget.
