Move LayoutCaches to ShareGroup Testing with TSN found a race condition with RefCounted objects (DescriptorSetLayout and PipelineLayout). Rather than add more lock calls to protect accesses to mRefCount and mObject recommendation was to put these caches in the ShareGroup (basically part of the context). Locking at the GL level will ensure that two threads that share the same context will not access the ShareGroup at the same time. The ShareGroup also works because these layouts are not destroyed until the context is destroyed so don't have to worry about other threads (e.g. command processor thread) accessing them.
