Add Memory Tagging Extension (MTE) support in kvmtool.

Changes since v2:

* Gathered Reviewed-by and Tested-by tags from Vladimir, thank you!
* Slight tweaks to the kvmtool debug and user messages.
* Do not set kvm->arch.cfg.mte_disabled is the MTE capability is not
  available. It is not used anywhere outside of the MTE setup function and
  kvm->arch.cfg is for user config options.

Changes since v1:

* Update headers to v5.17
* MTE capability is now enabled by default and the command line option
  --disable-mte has been added.

Sorry, b4 got confused by my scripts here. The SHAs are correct, but these
have obviously been applied to the kvmtool repository, not the arm64 kernel
tree!
