Remove several files from Recents Go src

As Go will not be using RecentsView, there are several files that are
unneeded in the recents Go source. This moves these files to
recents_ui_overrides where they will be used for non-Go builds.

Bug: 114136250
Test: Build NexusLauncher, aospWithQuickstep, l3GoWithQuickstep
Change-Id: I9d0154a75f4f2c71b865d414448e262b3019b2b9
