Suggestion to resolve build error in Mac Monterey 12.0.1

[ajay nair]

Hi team,

I tried to build chromium on MacOs Monterey 12.0.1 with m1 processor and it fails here: 

if (@available(macOS 13.0, *)) { collectionBehavior &= ~NSWindowCollectionBehaviorPrimary; } 

because NSWindowCollectionBehaviorPrimary is available only in MacOs 13 and later. I see that the line is surrounded with this if condition: 

if (@available(macOS 13.0, *)) { 

Shouldn't this be #if __MAC_OS_X_VERSION_MAX_ALLOWED >= 130000

 instead? If any of you agree, I can get a PR ready. Hopefully this can be the start of several contributions to chromium for me :)
