x86: Move gds_ucode_mitigated() declaration to header
The declaration got placed in the .c file of the caller, but that
causes a warning for the definition:
arch/x86/kernel/cpu/bugs.c:682:6: error: no previous prototype for 'gds_ucode_mitigated' [-Werror=missing-prototypes]
Move it to a header where both sides can observe it instead.
Fixes: 81ac7e5d74174 ("KVM: Add GDS_NO support to KVM")
