Extended version of Fred's patch to mark the APIC access page dirty on
VM-Exit (KVM already marks it dirty when it's unmapped).
v3:
- Fix a benign memslots bug in __kvm_vcpu_map().
- Mark vmcs12 pages dirty if and only if they're mapped (out-of-band).
- Don't mark the APIC access page dirty when deliver nested posted IRQ.
v2: https://lore.kernel.org/all/20250910085156.1419090-1-grif...

KVM: Use vCPU specific memslots in __kvm_vcpu_map()
KVM: x86: Mark vmcs12 pages as dirty if and only if they're mapped
KVM: nVMX: Precisely mark vAPIC and PID maps dirty when delivering
nested PI
KVM: VMX: Move nested_mark_vmcs12_pages_dirty() to vmx.c, and rename
