[PATCH RFC v9 05/51] x86/coco: move CONFIG_HAS_CC_PLATFORM check down into coco/Makefile

[Michael Roth]

Currently CONFIG_HAS_CC_PLATFORM is a prereq for building anything in
arch/x86/coco, but that is generally only applicable for guest support.

For SEV-SNP, helpers related purely to host support will also live in
arch/x86/coco. To allow for CoCo-related host support code in
arch/x86/coco, move that check down into the Makefile and check for it
specifically when needed.
