Fix 3 related races in SkColorSpace.cpp.

As written one thread can be comparing against, say, gSRGB, while
another thread is initializing it.  TSAN caught us.

To fix this, we funnel everything through a function that returns its
own local static, which is intialized on first use in a thread safe way.
