KVM: x86: Move PML page to common vcpu arch structure

Move the PML page pointer from VMX-specific vcpu_vmx structure to the
common kvm_vcpu_arch structure to enable sharing between VMX and SVM
implementations. Only the page pointer is moved to x86 common code while
keeping allocation logic vendor-specific, since AMD requires
snp_safe_alloc_page() for PML buffer allocation.

Update all VMX references accordingly.

No functional change, restructuring to prepare for SVM PML support.
