Improve SingletonThreadLocal performance

Summary:
[Folly] Improve `SingletonThreadLocal` performance.

By explicitly controlling inlining behavior.

The ctor is definitionally cold - once per process - so outline.

`get` is hot so inline. Uncached `get` is cold - once per thread - so outline uncached.
