[Documentation] Update Ozone Overview to mention BUILDFLAG differences

Updates the Ozone Overview documentation to explicitly specify the
differences between the IS_OZONE and IS_OZONE_WAYLAND buildflags.

IS_OZONE_WAYLAND should only run on Linux systems using the Wayland
window manager. Does not include ChromeOS or Fuchsia.
