qemu-system-aarch64 default pointer authentication (QARMA5) is expensive, we
spent up to 50% of the emulation time running it (when using TCG).

Switching to pauth-impdef=on is often given as a solution to speed up execution.
Thus we talked about making it the new default.

The first patch introduce a new property (pauth-qarma5) to allow to select
current default algorithm.
The second one change the default.
The third one updates documentation.

v2:
- ensure we don't break migration compatibility, by using a specific backward
   compatible property.
- added some documentation about migration for arm virt machine model.

Other than a minor change to the 3rd docs patch which I'll note there:
applied to target-arm.next, thanks.

Thank you Peter.
