KVM: x86/mmu: move cr4_smep to base role
Guest page tables can be reused independent of the value of CR4.SMEP
(at least if WP=1). However, this is not true of EPT MBEC pages,
because presence of EPT entries is signaled by bits 0-2 when MBEC
is off, and bits 0-2 + bit 10 when MBEC is on.
In preparation for enabling MBEC, move cr4_smep to the base role.
This makes the smep_andnot_wp bit redundant, so remove it.
