CPLAT-8122 Shorten propTypes boilerplate

[aaronlademann-wf]

Motivation

The Component2.propTypes boilerplate was unnecessarily verbose.

Changes

1. Add a class that contains the metadata that was previously provided as separate arguments, and change the PropValidator typedef signature to only require two arguments - with the second argument being an instance of the metadata class.

   Before:

   @override
   get propTypes => {
     'name': (Map props, propName, componentName, location, propFullName) {
       if (props[propName].length > 20) {
         return ArgumentError('...');
       }
       return null;
     },
   };

   After:

   @override
   get propTypes => {
     'name': (Map props, info) {
       if (props[info.propName].length > 20) {
         return ArgumentError('...');
       }
       return null;
     },
   };

2. Update JS interop to pass through the field values from the ReactValidatorInfo fields as individual arguments to the JS React.propTypes function.

3. Update some dynamic call sites where they could be tightened to at least Function.
