Currently the TCGCPUOps::cpu_exec_halt method is optional, and if it
is not set then the default is to call the CPUClass::has_work
method (which has an identical function signature).
We would like to make the cpu_exec_halt method mandatory so we can
remove the runtime check and fallback handling. In preparation for
that, make all the targets which don't need special handling in their
cpu_exec_halt set it to their cpu_has_work implementation instead of
leaving it unset. (This is every target except for arm and i386.)
In the riscv case this requires us to make the function not
be local to the source file it's defined in.

for which PAGE_RWX is a better name and renaming it also shows it is

We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

Since CPU() macro is a simple cast, the following are equivalent:
Object *obj;
CPUState *cs = CPU(obj)
In order to ease static analysis when running
scripts/coccinelle/cpu_env.cocci from the previous commit,
replace:
- CPU_GET_CLASS(cpu);
+ CPU_GET_CLASS(obj);
Most code use the 'cs' variable name for CPUState handle.
Replace few 's' -> 'cs' to unify cpu_reset_hold() style.
No logical change in this patch.

For all targets, the CPU class returned from CPUClass::class_by_name()
and object_class_dynamic_cast(oc, CPU_RESOLVING_TYPE) need to be

instead of having the check in CPUClass::class_by_name() for individual
target.

The OBJECT_DECLARE_CPU_TYPE() macro forward-declares each
ArchCPUClass type. These forward declarations are sufficient
for code in hw/ to use the QOM definitions. No need to expose
these structure definitions. Keep each local to their target/
by moving them to the corresponding "cpu.h" header.

The first declaration of a storage or class structure should

backing for properties (options driven by the user) and internal
