i386/cpu: Reorganize arch lbr structure definitions

- Move ARCH_LBR_NR_ENTRIES macro and LBREntry definition before XSAVE
  areas definitions.
- Reorder XSavesArchLBR (area 15) between XSavePKRU (area 9) and
  XSaveXTILECFG (area 17), and reorder the related QEMU_BUILD_BUG_ON
  check to keep the same ordering.

This makes xsave structures to be organized together and makes them
clearer.
