i386: Add Icelake-Server-v6 CPU model with 5-level EPT support 

Windows 11 with WSL2 enabled (Hyper-V) fails to boot with Icelake-Server
{-v5} CPU model but boots well with '-cpu host'. Apparently, it expects
5-level paging and 5-level EPT support to come in pair but QEMU's
Icelake-Server CPU model lacks the later. Introduce 'Icelake-Server-v6'
CPU model with 'vmx-page-walk-5' enabled by default.
