Introduce an x86 version of the prot_guest_has() function. This will be used in the more generic x86 code to replace vendor specific calls like sev_active(), etc.

While the name suggests this is intended mainly for guests, it will also be used for host memory encryption checks in place of sme_active().

The amd_prot_guest_has() function does not use EXPORT_SYMBOL_GPL for the same reasons previously stated when changing sme_active(), sev_active and

None of that applies here as none of the callers get pulled into random macros. The only case of that is sme_me_mask through sme_mask, but that's not something this series replaces as far as I can tell.

Ok, let me make sure of that and I'll change to EXPORT_SYMBOL_GPL if that's the case.

Thanks, Tom
