Nirbheek Chauhan bb32532f60 applemedia: Disable 64RGBALE support on older macOS
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().
