x86/spec-ctrl: Rework spec_ctrl_flags context switching

We are shortly going to need to context switch new bits in both the vcpu and
S3 paths.  Introduce SCF_IST_MASK and SCF_DOM_MASK, and rework d->arch.verw
into d->arch.spec_ctrl_flags to accommodate.

No functional change.

This is part of XSA-407.
