x86/tdx: Detect running as a TDX guest in early boot

boot

x86/tdx: Detect running as a TDX guest in early boot

In preparation of extending cc_platform_has() API to support TDX guest,
use CPUID instruction to detect support for TDX guests in the early
boot code (via tdx_early_init()). Since copy_bootdata() is the first
user of cc_platform_has() API, detect the TDX guest status before it.

Define a synthetic feature flag (X86_FEATURE_TDX_GUEST) and set this
bit in a valid TDX guest platform.

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.
