When running under KVM, we may decide to run the CPU in 32-bit mode, by
setting the 'aarch64=off' CPU option. In this case, we need to switch to
the 32-bit version of the GDB stub too, so that GDB has the correct view
of the CPU state. Without this, GDB debugging does not work at all, and
errors out upon connecting to the target with a mysterious 'g' packet
length error.

v2: refactor existing CPUClass::gdb_... member assignments for the
32-bit code so we can reuse it for the 64-bit code
