Central point for static initialization.
In case of "lazy" mode `BrotliXxxLazyStaticInit` is not provided by the
library. Embedder is responsible for providing it. This function should call
`BrotliXxxLazyStaticInitInner` on the first invocation. This function should
not return until execution of `BrotliXxxLazyStaticInitInner` is finished.
In C or before C++11 it is possible to call `BrotliXxxLazyStaticInitInner`
on start-up path and then `BrotliEncoderLazyStaticInit` is could be no-op;
another option is to use available thread execution controls to meet the
requirements. For possible C++11 implementation see static_init_lazy.cc.
