x86/cc: Move arch/x86/{kernel/cc_platform.c => coco/core.c}
Move cc_platform.c to arch/x86/coco/. The directory is going to be the home space for code related to confidential computing. Intel TDX code will land here. AMD SEV code will also eventually be moved there. No functional changes. Signed-off-by: Kirill A.
