2023-11-07hw/cpu: Call object_class_is_abstract() once in cpu_class_by_name()Philippe Mathieu-Daudé
Let CPUClass::class_by_name() handlers to return abstract classes, and filter them once in the public cpu_class_by_name() method.

2023-11-07target: Move ArchCPUClass definition to 'cpu.h'Philippe Mathieu-Daudé
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.

2023-11-07target: Declare FOO_CPU_TYPE_NAME/SUFFIX in 'cpu-qom.h'Philippe Mathieu-Daudé
Hegerogeneous code needs access to the FOO_CPU_TYPE_NAME() macro to resolve target CPU types. Move the declaration (along with the required FOO_CPU_TYPE_SUFFIX) to "cpu-qom.h". "target/foo/cpu-qom.h" is supposed to be target agnostic (include-able by any target). Add such mention in the header.

2023-11-07target: Unify QOM stylePhilippe Mathieu-Daudé
Enforce the style described by commit 067109a11c ("docs/devel: mention the spacing requirement for QOM"): The first declaration of a storage or class structure should always be the parent and leave a visual space between that declaration and the new code. It is also useful to separate backing for properties (options driven by the user) and internal state to make navigation easier.
