x86: debugctlmsr kconfig
This adds the (internal) Kconfig macro CONFIG_X86_DEBUGCTLMSR, to be defined when configuring to support only hardware that definitely supports MSR_IA32_DEBUGCTLMSR with the BTF flag. The Intel documentation says "P6 family" and later processors all have it. I think the Kconfig dependencies are right to have it set for those and unset for others (i.e., when 586 and earlier are supported).
