aura: Add support for touch events.

Among the changes:
. Add touch event handling in EventFilter. Be default, activates a window on TOUCH_START (like for MOUSE_PRESSED).
. Move TouchEvent details functions into ui/. Moved the X11 implementations from views/ to ui/. NOTIMPLEMENTED on windows.
. Disable RWHVAura et. al. for touchui for now (they are still compiled in, but not used).

BUG=100269
TEST=none
