target-i386: Use xsave structs for ext_save_area

Browse source 
This doesn't introduce any change in the code, as the offsets and
struct sizes match what was present in the table. This can be
validated by the QEMU_BUILD_BUG_ON lines on target-i386/cpu.h,
which ensures the struct sizes and offsets match the existing
values in ext_save_area.
