dynamic_debug: consolidate DEFINE_DYNAMIC_DEBUG_METADATA definitions
Instead of defining DEFINE_DYNAMIC_DEBUG_METADATA in terms of a helper
DEFINE_DYNAMIC_DEBUG_METADATA_KEY, that needs another helper dd_key_init
to be properly defined, just make the various #ifdef branches define a
_DPRINTK_KEY_INIT that can be used directly, similar to
_DPRINTK_FLAGS_DEFAULT.
