Nguyen Dinh PhiandPhilippe Mathieu-Daudé 3bee93b9ab accel/hvf: Fix i386 HVF compilation failures
Recent changes introduced build errors in the i386 HVF backend:

 - ../accel/hvf/hvf-accel-ops.c:163:17: error: no member named 'guest_debug_enabled' in 'struct AccelCPUState'
   163 |     cpu->accel->guest_debug_enabled = false;

 - ../accel/hvf/hvf-accel-ops.c:151:51
   error: no member named 'unblock_ipi_mask' in 'struct AccelCPUState'

 - ../target/i386/hvf/hvf.c:736:5
   error: use of undeclared identifier 'rip'

 - ../target/i386/hvf/hvf.c:737:5
   error: use of undeclared identifier 'env'

This patch corrects the field usage and move identifier to correct
function ensuring successful compilation of the i386 HVF backend.

These issues were caused by:

Fixes: 2ad756383e (“accel/hvf: Restrict ARM-specific fields of AccelCPUState”)
Fixes: 2a21c92447 (“target/i386/hvf: Factor hvf_handle_vmexit() out”)

Philippe Mathieu-DaudéandPeter Maydell 1182ede151 accel/hvf: Rename hvf_put|get_registers -> hvf_arch_put|get_registers
hvf_put_registers() and hvf_get_registers() are implemented per
target, rename them using the 'hvf_arch_' prefix following the
per target pattern.

Since they call hv_vcpu_set_reg() / hv_vcpu_get_reg(), mention
they must be called on the vCPU.

Paolo Bonzini d5e33b5f8f accel: make all calls to qemu_process_cpu_events look the same
There is no reason for some accelerators to use qemu_process_cpu_events_common
(which is separated from qemu_process_cpu_events() specifically for round
robin TCG).  They can also check for events directly on the first pass through
the loop, instead of setting cpu->exit_request to true.

Philippe Mathieu-Daudé b3b3ad22c8 accel/hvf: Include missing 'hw/core/cpu.h' header
Since commit d5bd8d8267 ("hvf: only update sysreg from owning
thread") hvf-all.c accesses the run_on_cpu_data type and calls
run_on_cpu(), both defined in the "hw/core/cpu.h" header.
Fortunately, it is indirectly included via:

  "system/hvf.h"
    -> "target/arm/cpu.h"
         -> "target/arm/cpu-qom.h"
              -> "hw/core/cpu.h"

"system/hvf.h" however doesn't need "target/arm/cpu.h" and we
want to remove it there. In order to do that we first need to
include it in hvf-all.c, otherwise we get:

  ../accel/hvf/hvf-all.c:61:54: error: unknown type name 'run_on_cpu_data'
   61 | static void do_hvf_update_guest_debug(CPUState *cpu, run_on_cpu_data arg)
