Merge remote-tracking branch 'remotes/rth/tags/pull-tcg-20211102' into staging

- Split out host signal handing from accel/tcg/user-exec.c
  to linux-user/host/arch/host-signal.h
- Replace TCGCPUOps.tlb_fill with TCGCPUOps.record_sigsegv for user-only
- Add TCGCPUOps.record_sigbus for user-only
- Remove a lot of target-specific cpu_loop handling for signals,
  now accomplished with generic code.
