hv: vmcs: simplify update EOI-exit bitmap

Browse Source 
1) The previous implementaion will recalculate the whole EOI-exit bitmap for
each RTE once the destination, trigger mode, delivery mode or vector of a RTE
has changed and update the EOI-exit bitmap for each vcpu of the VM.
In this patch, only set the corresponding bit of EOI-exit bitmap for
a vcpu when a level triggered interrupt has accepted in IRR or clear the
corresponding bit of EOI-exit bitmap for a vcpu when a dege triggered interrupt
has accepted in IRR which means only update a bit of EOI-exit bitmap in a vcpu
when updating TMR.
2) Rename set eoi_exit related API to set eoi_exit_bitmap.
