Make ShaderTranslatorCache per thread refcounted

After crbug.com/332146 is fixed, in Android WebView, GLES2Decoder can be
used on two threads. Make sure a ShaderTranslatorCache instance is only
used on a single thread by refcounting an instance between all decoders.

Also protect ShInitialize by using the thread safety guarantees of
LazyInstance.

For tests, a new instance of ShaderTranslatorCache is passed for each
ContextGroup.
