externals: Update Xbyak to 5.96

Browse source 
I made a request on the Xbyak issue tracker to allow some constructors
to be constexpr in order to avoid static constructors from needing to
execute for some of our register constants.

This request was implemented, so this updates Xbyak so that we can make
use of it.
