Update short cut pin state properly on Windows

[simonhong]

Resolves brave/brave-browser#26301

Polling the pinned state after asking to Windows because it's actually pinned
when user allowed via os notification.
We'll check 10 times with 2s interval after asking to Windows.
If user doesn't react or disallowed within that time, we doesn't change the state.
