Stacked on #32838.
We don't always type the Props of built-ins. This adds typing for most
of the built-ins.
When we did type them, we used to put it in the `ReactFiber...Component`
files but any public API like this can be implemented in other renderers
too such as Fizz. So I moved them to `shared/ReactTypes` which is where
we put other public API types (that are not already built-in to Flow).
That way Fizz can import them and assert properly when it accesses the
props.
