qom: register qdev properties also as non-legacy properties

Browse Source 
Push legacy properties into a "legacy-..." namespace, and make them
available with correct types too.

For now, all properties come in both variants.  This need not be the
case for string properties.  We will revisit this after -device is
changed to actually use the legacy properties.
