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.

We take the opportunity to move the syscall state into its own singleton instance and add in a few helpers for the main gdbstub to interact with the module.
