Merge tag 'exec-20241220' of https://github.com/philmd/qemu into staging

Accel & Exec patch queue

- Ignore writes to CNTP_CTL_EL0 on HVF ARM (Alexander)
- Add '-d invalid_mem' logging option (Zoltan)
- Create QOM containers explicitly (Peter)
- Rename sysemu/ -> system/ (Philippe)
- Re-orderning of include/exec/ headers (Philippe)
  Move a lot of declarations from these legacy mixed bag headers:
    . "exec/cpu-all.h"
    . "exec/cpu-common.h"
    . "exec/cpu-defs.h"
    . "exec/exec-all.h"
    . "exec/translate-all"
  to these more specific ones:
    . "exec/page-protection.h"
    . "exec/translation-block.h"
    . "user/cpu_loop.h"
    . "user/guest-host.h"
    . "user/page-protection.h"
