target-i386: Use xsave structs for ext_save_area
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.
