target/arm: fix exception syndrome for AArch32 bkpt insn
Debug exceptions that target AArch32 Hyp mode are reported differently
than on AAarch64. Internally, Qemu uses the AArch64 syndromes. Therefore
such exceptions need to be either converted to a prefetch abort
(breakpoints, vector catch) or a data abort (watchpoints).
