x86/cpuid: Handle leaves 0x8000000b-1a in guest_cpuid()

Leaves 8000000b-18 are reserved.  Leaf 80000019 is 1G TLB information and leaf
0x8000001a is performance hints.  These leaves have previously been hidden
from guests, but are perfectly safe to expose when appicable.

Update libxc to also expose these leaves.
