[roll] Roll fuchsia [kernel][lib] Use anonymous constraints for object cache API

Switch from SFINAE to C++20 anonymous requirements for the object cache
allocator API. The advantage of this change is that requirements can
detect if an ObjectCache instance can access a private ctor, due to
friendship with the allocated type, whereas SFINAE-based checks using
std::is_constructible cannot.

Aside from the improvement that simple friendship with ObjectCache
enables allocation using private ctors, there is no other runtime
behavior change.
