[PATCH-for-9.2] ui/cocoa: Temporarily ignore annoying deprecated declaration warnings

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

These warnings are breaking some build configurations since 2 months
now (https://gitlab.com/qemu-project/qemu/-/issues/2575):

  3 errors generated.

For the next release, ignore the warnings using #pragma directives.
At least until we figure the correct new API usage.
