Return unique_ptr's in ui/compositor/layer_unittest.cc factory functions

While adding a test to //ui/compositor/layer_unittes.cc, I noticed that
there are a bunch of factory functions that return raw pointers that the
call sites wrap in unique_ptr's. Changed them to return unique_ptr's to
make ownership more clear.

BUG=none
