Subject: [PATCH] Cocoa: No NSWindowStyleMaskResizable in fullscreen

On macOS 10.15 Catalina and earlier, not having the resizable bit
cleared in NSWindowStyleMask in fullscreen leads to windows minimising
when clicked anywhere in the content area.

On all tested macOS versions it also causes the fullscreen window to be
resizable by the user.

Regression introduced by 0d599026d04ddcc2695ae938fc1864523dab7a34.

Fixes #2377
Closes #2405

(cherry picked from commit 8e9a5d29a8258d2e82250102db9ae713794be321)
