accel/hvf: Include missing 'hw/core/cpu.h' header

Since commit d5bd8d8267e ("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'

This macro is used by only one target, and even then under

Since page size for aarch64-linux-user is variable, the
per-page data size is also variable.
Since page_reset_target_data via target_munmap does not
have ready access to CPUState, simply pass in the size
from the first allocation and remember that.
