fix(react): add fallback for SVG imports coming from non-TS/JS modules

[jaysoo]

This PR allows SVG files to be imported from non-JS/TS files (e.g. CSS) by using oneOf to use the rule that matches first.

I've added this to the next webpack config and tried it out, seems to work there too, although I had to add an index.d.ts file with this content:

declare module '*.svg' {
  const content: any;
  export const ReactComponent: any;
  export default content;
}

Is it worth adding this to the application schematic and creating it automatically for TS projects?

Also...how do we test this?
