Adapt to uBO's `scriptletGlobals` change from `Map` to object

[antonok-edm]

In https://github.com/gorhill/uBlock/commit/869a653fdf2dd4e5b0151530bd58e1059d1318d2#diff-b006827b72fe768a6cb08f3123783752a4a23ccc95c55467f24b77addac88a29R282, scriptletGlobals was modified to become a plain JS object instead of a Map.

As mentioned here, we'll need to use a Proxy object to restore compatibility with the older Map methods to ensure that users can migrate gracefully to the newer resource versions when we release them.

The above requires 1.62.159 or higher for 1.62.x verification(s) 👍
