spa: group the spa headers into doxygen modules Subdirectories buffer, control, debug, monitor, pod, support and utils, others are still missing. Headers are grouped either per subdirectory (e.g. buffer/ gets added to group spa_buffer) or per-file (e.g. spa_json is a separate group), whatever seemed like the most sensible approach.

More type cleanups SPA_ID_* -> SPA_TYPE_*. We use 'type' for all registered types. ID refers to either a registered type or an enum. Improve introspection of object ids. Make 0 an invalid enum and use it to look up the object id type. Move some type-info files together. Swap type and id of the object, we first specify the type and then the id because the meaning of the id depends on the object type.
