hw/arm/virt: Make EL3-guest accel check an accept-list
Currently only the TCG and qtest accelerators can handle an EL3
guest. Instead of making the condition check be "fail if KVM or HVF"
(an exclude-list), make it a be "allow if TCG or qtest" (an
accept-list).
This is better for if/when we add new accelerators, as it makes the
default be that we forbid an EL3 guest. This is the most likely to
be correct and also "fails safe"; if the new accelerator really can
support EL3 guests then the implementor will see that they need to
add it to the accept-list.
