Kristina Martsenko e0bb80c62c KVM: arm64: Expose MOPS instructions to guests ...

Expose the Armv8.8 FEAT_MOPS feature to guests in the ID register and
allow the MOPS instructions to be run in a guest. Only expose MOPS if
the whole system supports it.

Note, it is expected that guests do not use these instructions on MMIO,
similarly to other instructions where ESR_EL2.ISV==0 such as LDP/STP.
