x86/coco: Replace 'static const cc_mask' with the newly introduced cc_get_mask() function

When extra warnings are enabled, the cc_mask definition in <asm/coco.h>
causes a build failure with GCC:

  arch/x86/include/asm/coco.h:28:18: error: 'cc_mask' defined but not used [-Werror=unused-const-variable=]
     28 | static const u64 cc_mask = 0;

Add a cc_get_mask() function mirroring cc_set_mask() for the one
user of the variable outside of the CoCo implementation.

v2: use an inline helper instead of a __maybe_unused annotaiton.
