  ppc64: Avoid pt_regs struct definition

Remove pt_regs indirection and instead reference gp_regs directly, this
makes it portable across musl/glibc

Use PT_* constants defined in asm/ptrace.h

Move the file to ppc64 subdir and leave ppc empty

Fixes
../qemu-6.2.0/linux-user/host/ppc64/../ppc/host-signal.h:16:32: error: 
incomplete definition of type 'struct pt_regs'
    return uc->uc_mcontext.regs->nip;

  target/ppc: Replicate double->int32 result for some vector insns

Power ISA v3.1 formalizes the previously undefined result in
words 1 and 3 to be a copy of the result in words 0 and 2.

This affects: xscvdpsxws, xscvdpuxws, xvcvdpsxws, xvcvdpuxws.
