Move string ref coercion to JSX runtime
Based on:
- #28464
This moves the entire string ref implementation out Fiber and into the JSX runtime. The string is converted to a callback ref during element creation. This is a subtle change in behavior, because it will have already been converted to a callback ref if you access element.prop.ref or element.ref. But this is only for Meta, because string refs are disabled entirely in open source. And if it leads to an issue in practice, the solution is to switch to a different ref type, which Meta is going to do regardless.
