Make LM32CPU an opaque type within cpu-qom.h, and move all definitions of
private methods, as well as all type definitions that require knowledge
of the layout to cpu.h. This helps making files independent of NEED_CPU_H
if they only need to pass around CPU pointers.

Make cpu-qom.h so that it is only included from cpu.h. Then there
is no need for it to include cpu.h again.
Later we will make cpu-qom.h target independent and we will _want_
to include it from elsewhere, but for now reduce the number of cases
to handle.

This allows us to completely remove CPULM32State from DisasContext.
Instead, copy the fields we need to DisasContext.

Change breakpoint_invalidate() argument to CPUState alongside.
Since all targets now assign a softmmu-only field, we can drop helpers
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd().
Prepares for changing cpu_memory_rw_debug() argument to CPUState.

A transition from CPUFooState to FooCPU can be considered safe,
just like FooCPU::env access in the opposite direction.
The only benefit of the FOO_CPU() casts would be protection against
bogus CPUFooState pointers, but then surrounding code would likely
break, too.
This should slightly improve interrupt etc. performance when going from
CPUFooState to FooCPU.
For any additional CPU() casts see 3556c233d931ad5ffa46a35cb25cfc057732ebb8
(qom: allow turning cast debugging off).

Add a vmstate_lm32_cpu referencing the previous VMStateDescription as a
sub-struct and hook it up to CPUClass::vmsd. Drop cpu_{save,load}().

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.
It will also allow to override the interrupt handling for certain CPU
families.

Introduce ENV_OFFSET macros which can be used in non-target-specific
code that needs to generate TCG instructions which reference CPUState
fields given the cpu_env register that TCG targets set up with a
pointer to the CPUArchState struct.
