Don't run DirectRenderer versions of LayerTreeTest unless explicit.

Remove the direct variants from the SINGLE_AND_MULTI_THREAD_TEST_F
macros and friends, so you will only get a DirectRenderer if you
request it via SINGLE_AND_MULTI_THREAD_DIRECT_RENDERER_TEST_F and
similar macros.

Before, cc_unittests has 3366 tests. After, it has 3075.
