Replace assignmets to the window object with assingments to globalThis

VSCode and typescript still do not understand assignments to window as introducing of a global name. To make them happy, use assignment to globalThis.

I was waiting for so long, but seems like typescript will struggle with this kind of setup forever, especially when the world moves on to globalThis. So, here is a result of a routine replacement of window. with globalThis.. Now VSCode recognises all our global functions and it improves editing comfort.
