Revert "[Tizen] Prepare the screen orientation code to use the Blink impl"

This commit is not a requirement for moving to M36, so we can revert it
for now, have a much smaller squashed commit rolling DEPS.xwalk to M36
and then land it again.

This reverts commit 2684a4b2288ad679f14577de4457ba8cab001ee4.
Merge pull request #2010 from rakuco/revert-screen-rotation-pre-m36
