Replace globalScope with the standard globalThis property instead

Browse source 
Please see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis and note that most (reasonably) modern browsers have supported this for a while now, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis#Browser_compatibility

Since ESLint doesn't support this new global yet, it was added to the `globals` list in the top-level configuration file to prevent issues.

Finally, for older browsers a polyfill was added in `ssrc/shared/compatibility.js`.
