Cocoa: Fix clearing of unrelated window style bits
Whenever GLFW changed the window style mask, a new mask was created from scratch based on the attributes set on the GLFW window object. This caused us to potentially clear unrelated window style bits. This was always wrong but became a critical issue when Cocoa began throwing an exception if an application cleared the NSWindowStyleMaskFullScreen while the window is in macOS fullscreen. This commit reworks all style mask editing so it only changes the relevant bits, preserving all others. This is only a narrow bug fix to prevent crashes, intended for the stable branch. Our interaction with macOS fullscreen is still very poor. The next step after this is a set of patches that improve the interaction between the current API and macOS fullscreen. Fixes #1886 Fixes #2110
