x86/hvm: add HVM_PARAM_X87_FIP_WIDTH

The HVM parameter HVM_PARAM_X87_FIP_WIDTH to allow tools and the guest
to adjust the width of the FIP/FDP registers to be saved/restored by
the hypervisor.  This is in case the hypervisor hueristics do not do
the right thing.

Add this parameter to the set saved during domain save/migrate.
