tdf#161623 Handle windows that macOS forces to native full screen modeHEADmaster

Starting with commit c1452e73091412ba0bb72306329e1912df2ba513, native
full screen was disabled. However, in certain cases, macOS will force
a window into native full screen mode and this caused numerous bugs.

So add the following fixes to support native full screen windows. Note:
the green titlebar button will still zoom the window. That button will
only escape native full screen mode only when macOS has already forced
a window into native full screen mode:

- When in native full screen mode, -[NSWindow styleMask] will include
  NSWindowStyleMaskFullScreen which can affect the frame and content
  rectangle calculations so always use -[NSWindow styleMask] instead
  of the mask that was used to create the window when doing such
  calculations.

- A comment in commit c1452e73091412ba0bb72306329e1912df2ba513 mentions
  crashing after ordering out a native full screen window. I have not
  experienced any crashing, but I did find that ordering out would
  leave the application in a state where there is no Desktop and both
  the menubar and the Dock are hidden. The fix, which is to close
  windows instead of ordering them out, was copied from the following
  NeoOffice source code file which is licensed under the Mozilla Public
  License, v. 2.0:

  https://github.com/neooffice/NeoOffice/blob/NeoOffice-2022_7/vcl/java/source/window/salframe.mm

- In AquaSalFrame::GetWindowState(), add both the original and the
  curent frame when the window is in LibreOffice and/or native full
  screen mode.

- Track LibreOffice and native full screen state in separate instance
  variables so that both modes can be activated independently and the
  window is not set back to its original size unitl a window has exited
  both full screen modes.

LibreOffice also has its own full screen mode which hides the menubar
and Dock, resizes to fill the screen, and hides all of its toolbars.
As much as possible, both full screen modes should coexist and the
user can enter or exit LibreOffice full screen mode while in native
full screen mode. So add the following fixes for LibreOffice full
screen mode:

- Do not add the window's titlebar height to the window's frame as
  that will cause the titlebar to be pushed offscreen.

- The menubar and Dock are both hidden when a window enters LibreOffice
  full screen mode. However, -[NSWindow setFrame:display:] shrinks the
  window frame to allow room for the menubar if the window is on the
  main screen. So, force the return value to match the frame that
  LibreOffice expects.

- Multiple windows can be in LibreOffice full screen mode at the
  same time so hide or show the menubar and Dock when a LibreOffice
  full screen window gains or loses focus.

- When a window is in LibreOffice full screen mode, LibreOffice hides
  the menubar. However, when in native full screen mode, hiding the
  menubar causes the window's titlebar to either fail to display or
  fail to hide when expected. So allow the menubar to remain visible
  when a window is in both LibreOffice and native full screen mode
  and disable all LibreOffice menus (like is done when a modal windowj
  is displayed) to mimic the effect of hiding the menubar.
