cc: Remove the non-implside flavour of LayerTreeTests.

While doing so I audited a bunch of MULTI_THREAD only tests and turned
them into SINGLE_AND_MULTI_THREAD or documented why not to. Some of the
NOIMPL tests really are NOIMPL and I deleted them. The others I turned
on with impl-side instead.

NOTE TO PERF SHERIFFS: This changes the names of some cc_perftests and
makes some of them use impl-side painting now. If this has perf side-
effects these should be considered new (more accurate) baselines.
