The kCVPixelFormatType_64RGBALE enum is only available on macOS Big Sur (11.3) and newer. We also cannot use that while configuring the encoder or decoder on older macOS. Define the symbol unconditionally, but only use it when we're running on Big Sur with __builtin_available(). Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1613>
