Refactor Redbox, Logbox, and DevLoadingView as Sheets

[Saadnajmi]

Summary:

Upstream in React Native 0.74, RCTRedbox got heavily rewritten (see facebook@e2eb26c and facebook@b311c3e) . As such, we needed to update our macOS implementation. This proved to be quite difficult, as NSTableView is quite... obtuse. Many thanks to @FalseLobster for doing much of that part of the rewrite. I am cherry picking the rewrite commits here so we can reduce churn on the larger "0.74 merge" PR.

While we are touching this code, I realized that a natural presentation pattern for the red box would be to use a sheet. In fact, that would also apply to RCTDevLoadingView (which is particularly annoying as it's presented as a fixed-in-place tiny window on your screen) and RCTLogBox. So... I went ahead and refactored all three to use sheets. The result is quite nice!

While here, I realized separately, RCTRootView has a loadingView property so you can set something like an ActivityIndicator while it loads JS. There was some modifications to get that working, So I'm also adding that in this PR.

Test Plan:

RCTRedBox rewritten, and presented as a sheet:

RCTDevLoadingView and RCTLogBox presented as sheets:

RCTRootView.loadingView set to an NSProgressIndicator using the code block below. Ignore the devLoadingView looking different, I was testing a different design.

    NSProgressIndicator *loadingView = [NSProgressIndicator new]
    [loadingView setFrame:NSMakeRect(0,0,20,20)];
    loadingView.style = NSProgressIndicatorStyleSpinning;
    [loadingView startAnimation:self];
    [((RCTRootView *)rootView) setLoadingView:loadingView];
