macOS: Remove workaround for worksWhenModal not being reevaluated

Browse Source 
On macOS < 10.15 the worksWhenModal property of our NSWindow was read
on window initialization and propagated to the window server, but never
updated on the window server past that point, even if updating the
worksWhenModal property on the NSWindow.

Now that we no longer support macOS < 10.15, we can remove the workaround,
that was using private APIs to talk to the window server directly.

Pick-to: 6.5

// When creating an NSWindow the worksWhenModal function is queried,
// and the resulting state is used to set the corresponding window tag,
// which the window server uses to determine whether or not the window
// should be allowed to activate via mouse clicks in the title-bar.
// Unfortunately, prior to macOS 10.15, this window tag was never
// updated after the initial assignment in [NSWindow _commonAwake],
// which meant that windows that dynamically change their worksWhenModal
// state will behave as if they were never allowed to work when modal.
// We work around this by manually updating the window tag when needed.
