Add a four-element AsyncLocalValueMap type (#68790)

* Add a four-element AsyncLocalValueMap type

We previously special-cased up to three active AsyncLocals in a given async flow, but it seems four is also very common.  Special-casing four as well results in four using ~20% less allocation and ~10% less CPU overhead.

* Fix downgrading to FourElementAsyncLocalValueMap, and clean up source
