"target/foo/cpu-qom.h" can not use any target specific definitions.

Currently "target/sparc/cpu-qom.h" defines TYPE_SPARC_CPU
depending on the sparc(32)/sparc64 build type. This doesn't
scale in a heterogeneous context where we need to access both
types concurrently.

In order to do that, introduce the new SPARC32_CPU / SPARC64_CPU
types, both inheriting a common TYPE_SPARC_CPU base type.

Keep the current CPU types registered in sparc_register_cpudef_type()
as 32 or 64-bit, depending on the binary built.
