Merge migrate-to-apple-cf: phase 1-5 + v3.0.0

Long-pending migration of CMSampleBuffer/CVPixelBuffer/IOSurface/
CMTime/CMBlockBuffer/CMFormatDescription helpers into the new
apple-cf crate, plus extraction of Metal interop into the new
apple-metal crate.

screencapturekit::metal::MetalDevice::as_apple_metal() bridges the
SCK Metal renderer to the lightweight apple-metal crate without an
extra retain. screencapturekit::apple_metal re-exports apple-metal
for downstream code.

Verified: lib tests pass, full build succeeds against apple-cf v0.2
+ apple-metal v0.1.1.
