Keyboard patch: Enter types Return in app windows despite stale Steam search focus

Steam's VirtualKeyboardManager keeps the props of the last focused Steam text
field (m_ActiveElementProps) after leaving the dashboard. With a search box
there, the VR keyboard for a gamescope window showed "Search" on Enter and
its onEnterKeyPress returned "VKClose", hiding the keyboard instead of
sending Return. While the keyboard serves something other than this Steam
UI, ignore those props and the dismiss-on-Enter flag.
