Fix 4689527: Update Recents

Fixed layout in landscape mode where recents only filled half the screen
because "match_parent" in the layout was being ignored. The fix is to
have a temporary ViewGroup as the parent to ensure the layout parameters
are valid.

Changed to solid 70% opaque background on phone.

Removed "dismiss" chevron from phone layout.

Removes glow on phones.
