  x86/head/64: Switch to KERNEL_CS as soon as new GDT is installed (2023-06-02 16:59:57 -0700)

----------------------------------------------------------------
- Set up the kernel CS earlier in the boot process in case EFI boots the
  kernel after bypassing the decompressor and the CS descriptor used
  ends up being the EFI one which is not mapped in the identity page
  table, leading to early SEV/SNP guest communication exceptions
  resulting in the guest crashing
