Use 41% of screen height as all system VK height

Previously, accessibility keyboard uses 30 percent of screen
height as its height and compact keyboard uses 41 percent.

The IME VKs always use 41 percent for both full and compact
keyboards. This CL uses 41 percent for all system virtual
keyboards to make it consistent with IME VKs.
