[core] Standardize error messages across components

Create a utility to format a message and show an error to have consistency.
The most common case for now is a missing context. Errors should be handled in hooks (use*Context), optionally allowing the context to be absent, as in:

base-ui/packages/mui-base/src/Menu/Root/MenuRootContext.ts

Lines 19 to 28 in c66dcb1

    
           function useMenuRootContext(optional?: false): MenuRootContext; 
        
           function useMenuRootContext(optional: true): MenuRootContext | null; 
        
           function useMenuRootContext(optional?: boolean) { 
        
             const context = React.useContext(MenuRootContext); 
        
             if (context === null && !optional) { 
        
               throw new Error('Base UI: MenuRootContext is not defined.'); 
        
             } 
        
             return context; 
        
           }
