Add a fixer to fix type errors for --isolatedDeclarations

This code fixer fixes the following patterns.

1. Adding missing types on places that type can be explicitly annotated
2. Adding satisfies with type assertion on a value.
3. Create a namespace for expando functions and declare the property on
   the namespace.
4. Factor out expressions in heritage clauses (class B extends <expression>)
   and give them separate names.
