Use frame instead of visibleRect

[rib]

This backports an upstream macOS backend fix (rust-windowing#3043) that avoids referring to the visibleRect for knowing the new size of a view after a resize since that may have a spurious / invalid size. Instead winit checks the view's .frame() rectangle.

just for reference here; I rebased and force pushed the ark-staging branch to avoid the merge commit while I prefer to have ark-staging just be a stack of rebased commits for when it comes to updating to later winit releases (will likely manage updates in terms of rebasing / cherry-picking any changes we need to keep for winit 0.29 as opposed to having a long-running branch where we merge master back in - otherwise it may get awkward to keep a clear view of our local changes that aren't upstream)
