Simple WindowManager that can move/resize window.

Fixes TouchFrame's NonClientHitTest to ignore VirtualKeyboard area.
Move mouse capture logic to Window Manager so that nested
mouse capture with nested NWVs works correctly.

Note1: This is a tentative WM that allows us to move/resize window in views desktop until we have real window manager based on aura/layer API.

Note2: There is an compositor related issue and doesn't work well when compositor is enabled. I'll look into it after this CL.
