Add declaration files for each component which must contain the props declaration for the component

1. Add a declaration file eg. Button.d.ts for each component and extract the types into that file.
2. If the types don't exist yet in the original component file, create them yourself seeing the code, they're fairly simple at this point.
3. Use those types in the original component file by importing them.
