enhance(core): use sync commands for window and webview getters

[Legend-Master]

Reference: #12032

I don't quite know the reason behined why all window and webview commands are async, seems like for the setters, they would trigger events during the call and causing dead locks, but I can't see any reason for the getters, let me know if this was actually intentional or not

I believe we used to have them sync but it caused dead locks somewhere, I think @lucasfernog has more info about this

I'm pretty sure we'll have deadlocks if we do this :/

I'm pretty sure we'll have deadlocks if we do this :/

Do you know any particular places where the deadlock will happen?

If we can't fix them, maybe it's a good idea to document the problem, I have encountered this before trying to call window.center in a sync command and it's quite frustrating trying to debug it
