RFC: Context should accept non-children props as value

[Gokul-Gireesh]

This RFC proposes allowing React Context to accept non-children props as the provided value.

• Keeps value for backward compatibility.
• If no value is passed, all non-children props become the context value.
• Excludes children from injection.
• Simplifies context usage and makes it consistent with normal prop-passing in React.

Example:

<MyContext foo={foo} bar={bar}>
  <App />
</MyContext>

Consumer:

const { foo, bar } = useContext(MyContext);
